The best Gaming PCs are a topic of great interest by gamers. Nowadays, the world has taken the first steps in the modern technological life flow, and humanity is also very quickly integrated into that flow. Therefore, the computer also has a rapid improvement in configuration to meet the increasing needs of users.

Up until now, good gaming computers have always been the most concerned about their internal components before judging their appearance. And synchronous computer manufacturers understand this, too. They compute and create the best gaming PC suite for users' gaming performance.

Today, we're introducing you to some of the best Gaming PCs suites in the world right now. And of course, these Gaming PCs sets will meet all the highest-configuration games like The Witcher 3: Wild Hunt or Ghost of Tsushima, or even RED DEAD REDEMPTION 2...

The following article from JustGage experts on the topic of the best Gaming PCs will help you get an overview and objective suggestions to choose a product that suits your needs and budget!

Buying Guides

Answering the question "what are the best gaming PCs", we can roughly say that the computers are optimized for the gaming performance of each component used when building a configuration. These components are carefully selected and carefully calculated for each of the specifications for the best compatibility with each other. From there, awesome PC Gaming suites are built at the best cost savings and with the best gaming performance.

In addition, users can also create their own awesome gaming PC thanks to their understanding of computers. We can buy individual components and combine them in many different styles. Most importantly, the components are compatible with each other and selected on the basis of the capabilities of each part.

And from then on there will be a wide variety of configurations built on top of the best gaming PC components available today. Different manufacturers will have a combination of different brands of RAM, mainboard, hard drive, cooling system, and computer source to create their products. 

But before building the best gaming PC, one thing is that most gamers often start to learn from the expensive components in the market. This is both time consuming and difficult to choose, and if your budget does not allow it, buying an expensive gaming PC is even more difficult. So, you should start by defining your budget and your needs. It will help you to localize and make it easier to determine PC suite priorities:

  • CPU processor

The CPU's function is to process information and the faster it can be processed, the smoother your game will run. CPU speed (known as clock speed) is measured in hertz quantities like Gigahertz (GHz) or Megahertz (MHz). CPUs often cannot be upgraded, so it is important to choose the best CPU for gaming if you upgrade other components later. For today's best gaming CPUs, you can refer: AMD Ryzen 5 5600XAMD Ryzen 9 5950XIntel Core i7-10700KAMD Ryzen 9 5900X, or AMD Ryzen 5 3600X.

  • GPU 

The best gpu for gaming makes your PC play better. The graphics card is the component that gives you the most attention for your gaming PC. This is the component that has the biggest effect in beautifying your games, increasing the high frame rate and making the resolution higher.

If you are interested in gaming 4k or more than 100 FPS, then the choice of VGA in the new generation is inevitable. It is the GTX 16-series, Nvidia's RTX 20 GPU and AMD's RX 5000-series. An often confusing factor of a graphics card is memory. It's easy to figure out how much system RAM you need, but the GPU is a bit harder to decide. You may even find yourself having a choice between two similar graphics cards that offer different memory offerings. More memory doesn't have a noticeable impact on overall performance, but it does allow a video card to handle some of the imaging features slightly better.

Some of the best graphics cards for you: 

Nvidia GeForce RTX 3060 Ti: The best graphics card.

Nvidia GeForce RTX 3080: The best graphics card, hands-down.

Nvidia GeForce RTX 3090: The best graphics card for creatives.

AMD Radeon RX 5600 XT: One of the best graphics cards of all time

  • RAM

And finally, avoid wasting unnecessary money on RAM. When using 64GB of RAM for PC gaming, that's completely redundant. Just 16GB of RAM is enough for a good gaming PC. But you can still use 8GB of RAM if you're playing older games or don't mind sacrificing detail or frame rate to save extra budget. You can refer best RAM for gaming

TEAM XTREEM ARGB 16GB DDR4-3600MHz: The best RAM for gaming.

Corsair Dominator Platinum RGB 32GB DDR4-3200MHz: The best high-end RAM for gaming.

G.Skill Trident Z Neo 32GB DDR4-3600MHz: The best RAM for gaming with an AMD motherboard.

G.Skill Trident Z Royal 16GB DDR4-4000MHz: The best high-frequency RAM for gaming

In a moment we will introduce to you the best Gaming PCs available today. All have the best and most optimized Gaming performance. You can play games at the highest graphics settings with 8K resolution for all current PC games.

According to Asetek, the Alienware Aurora R11 system is equipped with AIO water cooler for both the CPU and GPU. However, they are completely "independent" water cooling systems with their own radiators. As for CPU water coolers, they're still the traditional AIO heatsinks before.

However, the GPU heatsink is a completely new product, they will place the Radiator right below it and connect them to the PCI-e slot on the motherboard and Asetek calls it the Card Radiator. Asetek shared that this Card Radiator heatsink system will take wind directly through the fans on the video card, which means that the Card Radiator only contains a Radiator, the fan system. Heat, pump,… are all located on the video card. In terms of performance, Asetek says they reduce noise by up to 69% and improve temperatures by 20%.

With such a design, when looking from the outside, everyone thinks that Alienware Aurora R11 uses 02 video cards, but in fact, there is only 01 video card and the "fake" video card below is just Radiator heatsink only!

This unique design by Asetek not only brings aesthetics but they also make the Alienware Aurora R11 system look more aggressive, more powerful when viewed from the outside. That gives you a range of Alienware gaming machines from affordable 1080p gaming right up to blistering 4K performance, and the Alienware AIO cooling system will help keep the cozy interior of the case at a reasonable temperature too.

4. Dell Inspiron G5 5090 - Affordable price, great experience

Dell G5 5090 is one of the products that gives you a powerful gaming device with an affordable price but excellent configuration, which satisfies most today's heavy games thanks to its outstanding performance. Dell G5 5090 is one of the first names you should think of when looking for a gaming desktop.

  • Dell G5 5090 Gaming Desktop: Outstanding coloration is what gamers are very interested in when choosing to buy accessories for Gaming PCs. Understand that, the Dell G5 5090 Gaming Desktop is also prominent with a blue light strip that is very catchy on the front, the transparent side can see through the internal components arranged extremely. neat and beautiful.
  • Dell G5 5090 PC case has a quite compact design that is quite suitable for small area rooms. On the left side of the tower is a single plastic window. You can see the internal components lit by blue LEDs, giving the impression that the G5 is a high-end gaming desktop.

What we also like about the G5 desktop is the ports on the front panel. On the front, there are 3.5 mm audio jack, 3.5 mm mic jack, one USB-C port and three USB-A ports. On the back, you'll find six USB-A ports - four USB 3.1 and two USB 2.0. In terms of connectivity, the desktop comes with Bluetooth 4.2 connectivity and a Qualcomm DW1810 chip for 802.11ac wireless connectivity inside. In addition, there are HDMI port, DVI port, Ethernet port, DisplayPort.

Also, for anyone who regularly needs to upgrade their PC system, the Dell G5 5090 will be very convenient because you can upgrade quite well. You can add additional RAM or switch GPU on PC. It has two RAM slots, so it can upgrade the Ram up to 64GB.

The G5 is a dedicated gaming PC, and that means its performance is best for running graphics-intensive games. In our week-long test, this gaming PC went through medium to high workloads. We mainly use the G5 to browse the web, edit documents, watch YouTube and Netflix and of course play games and everything is pretty smooth. Some Dota 2, PuBG games are doing pretty well. The RTX 2060 graphics chip is powerful enough to keep games at relatively heavy levels running smoothly and perfectly.In terms of software, the Dell G5 runs on Windows 10. But Dell has also added a piece of software called the Alienware Command Center, which will be helpful for monitoring system performance.

Not everything is perfect for the Dell G5 Gaming PC, though. The Dell G5 is equipped with a 460W power supply unit (PSU). Although the 460W power supply will be fine for current hardware, we also suspect this PSU will not be enough when users want to upgrade more RAM or GPU. In short, the G5 still has limitations when it comes to upgrading all other components besides the CPU, GPU, and RAM.

The Dell G5 5090 is clearly made for people who don't have the time or money to build a gaming desktop but still want a reliable desktop with plenty of ports, good performance.

5. Gaming Desktop Dell Inspiron 5680 - Cool design, powerful configuration

1. What is the most important component on PC Gaming?

Gaming graphics cards and CPUs are two of the many important components of a gaming computer. A great PC Gaming is judged by how well equipped the video card is and how well the CPU is supported.

  • Pay attention to graphics cards: Most casual gaming systems will come pre-loaded with a single mid-range or high-end graphics card. Systems with higher prices will naturally have better cards, as price is often correlated with configuration performance and image processing quality.
  • CPU processor as powerful as VGA: The best PC Gaming in the world today are equipped with extremely powerful CPUs with clock speeds up to 5.00 GHz. And stand out is the top line of CPU generation 9 and 10 from Intel. Two names are known as the Intel Core i9-10900K CPU - the world's fastest CPU currently reaches 5.3 GHz and i9-9900K also offers equally high speeds when overclocked. The processing clock speed greatly affects the gaming performance of the gaming PC system.

2. Besides the VGA and CPU, what else should I upgrade?

The answer is RAM and hard drive storage, of course!

  • RAM

An important but often overlooked factor on gaming systems is RAM. RAM plays a very important role in helping systems handling modern games consume a lot of memory. Considering the practical requirements of today's games, you must equip your system with at least 8GB to 16GB of RAM if you don't want to run into problems with stuttering, lag or reloading programs.

Faster memory will also help improve overall performance and help keep the CPU running more stably in case you decide to overclock. For example, a DDR4-3200 SDRAM stick is definitely more stable than a DDR4-2133 stick if you overclock your Core i7 processor. That's why having a higher-priced, more expensive memory doesn't always keep the CPU running smoothly, so make sure you use your budget wisely.

  • Hard drives

Solid-state drives (SSDs) have been used more commonly since the price of this product line began to drop significantly in the past few years. Hard drives with higher read and write speeds will be able to boot the system and load applications faster.

However, the selling prices of large capacity SSDs are still quite high. Therefore, using the combination of both SSD and HDD will give better economic efficiency. For example, a system using a 128GB SSD coupled with a 1TB HDD is a good, affordable setup for gamers in everyday use.

3. I am very interested in computer cases, any advice?

Computer case is the thing when building computers that people usually don't care about most. The camera case greatly affects your daily experience and use such as: The finish quality of the shell, whether the paint is beautiful or not, looks seamless and easy to peel. The good visual experience is also a factor that creates excitement when entertaining the user. So we recommend that you choose according to the following 3 criteria:

  • The certainty of the chassis: Whether the shell material is sturdy enough or not, whether the chassis is solid. This is important because if the chassis is too light or the chassis is too weak, the case will easily be shaken by the CPU fan, VGA fan and chassis fan, creating very annoying noise during operation. process using.
  • Large inside: Easy to attach components, easy to wire. A chassis that's narrow, has too few slots to mount the hard drive, or an inconvenient mounting position will all make it difficult to fit components into the chassis. That difficulty will continue until you start walking here inside the bin, neatly, nice and safe. Please go to the website of the company to preview the interior of the chassis before deciding to buy it or consult a professional. Note that narrow cases are also the cause of the warming of the components inside the computer. So we recommend choosing the coolest case possible.
  • Can many fans be attached? This is important, affects the cooling effect of the chassis. For example, if you put the tail of the chassis close to the wall, you should prioritize the chassis with a fan mounted on the top and front edges so that the air can easily circulate, the chassis can easily bring the heat out and bring cool air inside. This not only heats the device but can affect its internal components.

4. Should I invest in Gaming PC configuration for 4K games and virtual reality?

High-end GPUs will cost you no less than a few hundred dollars depending on the model. In addition to adding more power to your gaming experience, multiple graphics cards also support multi-monitor setups so you can run up to six monitors at once (although gamers are rewarding only. use up to three monitors).

Therefore, to avoid redundancy in performance, you can consider choosing high-end monitors to better handle 4K games and virtual reality (VR) glasses for a long time. The panels have a resolution of 4K (3,840 x 2,160 pixels) and the screen is integrated with VR glasses for a much higher pixel density than regular 1080p HD screens, so of course you will also love need higher graphics processing power.

You'll need at least a high-end graphics card to drive a 4K display at high quality settings, with similar requirements for a smooth experience on VR. If you want to experience a good gaming experience on a 4K display with detailed configuration settings, there will be few better choices than Nvidia's most high-end products, be it a GeForce GTX 1080 Ti or a in AMD "Turing" cards coming out as expected.

VR headsets will have their own graphics requirements, but for the two most prominent products today from HTC and Oculus, you'll need to have at least a GeForce GTX 1060 or AMD Radeon RX 480 or Radeon RX 580 is new enough for VR to function properly.

Not much more, VR and 4K games will require high-end hardware components. Of course you can still get a rich gaming experience and still save a thousand dollars by choosing a desktop with a mid-tier CPU that's powerful enough to game at resolution. 1080p or 1440p. If you are less concerned with VR then lower end graphics cards and GPUs will still give you excess power.

5. What's the difference between a prebuilt Gaming PC and a free-build Gaming PC?

  • Gaming PC free-build

Most gamers have that hobby is to build up the best gaming computer system at the lowest price possible for themselves. In addition to choosing new types of devices and machines to build gaming computers, nowadays, building desktop sets with old items is also a trend of choice for gamers.

Saving a lot of costs for buying machines, old gaming computers also allow people to build gaming computers in different styles to satisfy their passions and preferences while still ensuring performance. of the system.

  • Gaming PC pre-built

It is known for its stability and durability, not only that, synchronous PC products are often designed scientifically and eye-catching. Currently, there are also a number of major computer manufacturers such as Dell, Asus .. have launched synchronous computer lines, workstations for users to do graphics and play games and it also brings feedbacks. extremely positive feedback from the gaming community.

The advantage of the pre-built Gaming PC is that you can be completely assured of the quality as well as the harmonious coordination between the components of the synchronous computer. Gaming PC pre-built has high aesthetics, eye-catching design, sleek design, and the ability to unify its components.

Gaming PC pre-built also integrates proprietary software to help you use your computer stably without having to deal with non-genuine software. The computer performance is maximized and durable compared to other models.

Overall, gaming PC pre-built is great for less computer savvy audiences, as it comes pre-assembled and meticulously tested. However, pre-built Gaming PCs usually cost more than buying components for yourself because high quality and durability products often come with price and most importantly, it’s difficult to upgrade components because it relates to the compatibility between components.
