Velztorm Archux – Cheapest Option

The last recommendation for the pre-built gaming PC with RTX 3090 is for those who are looking for the cheapest possible option. First of all, keep in mind that we are talking about an RTX 3090-based gaming PC, so don’t expect to have a very, very low price as the RTX 3090 GPU alone costs around $1500. So, this cheapest PC may also look expensive to some gamers.

Velztorm Archux
Velztorm Archux

  • Processor: AMD Ryzen 7 3700X
  • GPU: NVIDIA RTX 3090 24GB VRAM
  • RAM: 16GB DDR4
  • Storage: 1TB NVMe SSD
  • Weight: 11.2 lbs, RGB Case: Yes

I am talking about the Velztorm Archux prebuilt gaming PC. This PC comes with the AMD Ryzen 7 3700X CPU with 8 cores and 16 threads. The CPU is definitely pretty powerful and can be a companion of the RTX 3090. This processor has a base clock speed of 3.6GHz and can be boosted up to 4.4GHz. This processor is based on the Zen2 architecture from AMD instead of Zen3, but it still is fabricated over the 7nm node to make it power efficient. The PC also has a 120mm AIO Liquid CPU cooler, which is strange but will definitely help you upgrade your CPU to a more powerful one.

Regarding the memory, there is 16GB of DDR4 RAM, which is enough for lag-free gaming. And the storage of the PC ranges to 1TB of NVMe m.2 SSD. Being the cheapest RTX 3090 PC, there are limited resources supplied with this PC, such as an outdated processor, limited RAM, etc.  So, the lower price always comes with some compromises. Eventually, you have to decide whether you want best-in-class hardware or a lower price. Personally, we don’t highly recommend this PC.

Pros
  • Pocket Friendly
  • Attractive Design
  • Liquid Cooling
  • Acceptable Performance
Cons
  • Comparatively Weak Processor
  • Restricted Memory
  • WiFi Unavailable

Buying Guide: How to Choose the Best RTX 3090 Gaming PC?

It’s not only about the RTX 3090 that will be needed to game intensively. There are a lot of other hardware components and factors that will make or break your gaming empire. Hence it becomes really very important to pay attention to the rest of the hardware as well. Otherwise, a compromise on the rest of the hardware will put your PC in the situation of bottlenecking and eventually leading to partial use of the RTX 3090’s power. So here are the things that one should keep in mind and look for while buying a prebuilt gaming rig with an RTX 3090.

Processor

This is the primary component due to which the PC does all the calculations and tasks. Being one of the main components, compromising on it can lead to a sure-shot low performance. And when it comes to a good CPU that can accompany the RTX 3090, it should have a good multi-core design, a good clock speed, and should also be power efficient. Try to look for a CPU that comes with at least 8 cores and 16 threads with a minimum base clock speed of 3.0GHz.

It’s your personal preference whether you want to go with an Intel CPU or AMD’s. The latest-gen CPUs of both the companies are really capable. And if you ask me, I would suggest you go for an AMD Ryzen 9 5900 CPU as it not just performs well in games but is also good for multi-threaded productivity tasks. You can definitely go with Intel Core i9 to match the performance of RTX 3090. Overall, that’s your personal choice. Both Intel and AMD have some powerful processors in their portfolios.

RAM

Talking about the RAM on a PC, its capacity and speed majorly decide how the PC is gonna perform in opening heavy games and software. In short, the RAM plays a key role in deciding the multitasking capability of a PC. Covering the aspect of RAM capacity, a high-end gaming PC with one of the best desktop GPUs, the RTX 3090, should come with no less than 16GB of RAM. This is the bare minimum a heavy gaming PC should have.

However, to have a good performance and multitasking, 32GB of RAM is advised. The speed or frequency of the RAM also matters. The faster the RAM, the faster it will perform in multitasking. Never settle below DDR4 RAM that runs at a minimum of 2933MHz. A RAM below this base specification will surely put you in a bottlenecked scenario.

Storage

When the whole PC is high-end, and it is capable of crushing any game, you throw. It is obvious that you will play big-sized games. Hence the PC will also need a huge storage solution to install these games. And for this specific RTX 3090-based gaming PC, having 1TB of SSD storage is a must. Most PC builders also provide additional HDD storage of 1TB to 3TB that can store occasionally used data and game files for future use.

Aesthetics

When you’re spending thousands of dollars on a gaming PC, its looks and aesthetics also matter. A PC whose performance is awesome but doesn’t look that appealing even after spending a huge chunk of money will definitely satisfy a gamer’s desires. Hence in my personal opinion, a gaming PC should also be as good as it performs. Gaming PCs come in different visual styles and sizes but what they should have at minimum is a good and cool-looking RGB factor.

Water cooling or normal cooling

This can be a big doubt whether to have a water-cooled PC, or a conventional Air-cooled PC is enough. And the answer depends on what processor the PC is having. Normally, the pre-built gaming PCs with a water cooling solution only come with the water-cooled CPU. And if your processor is top of the line and high-performing like the core i9 or Ryzen 9, having a water-cooled CPU will definitely serve the purpose.

But if you are opting for a gaming PC with a slightly compromised Intel or AMD CPU like the Core i7 or Ryzen 3000 series processor, the Air-cooled PC will get the job done. You can get water cooling when you upgrade your CPU to a more powerful one.

Frequently Asked Question (FAQs)

Why do I need an RTX 3090 PC? For just gaming or any other work?

If you are buying RTX 3090 PC just for gaming, it is not the right idea. This is just an insane graphics card that overkills any game available on this planet. But if you need a productivity workstation along with a powerful gaming PC, this GPU works like a charge. You can run any CAD-based software, such as AutoCAD, Solidworks, Blender, or any other CAD-based software. Also, this is an ideal GPU for 3D modeling and other graphics-intensive professional work.

Is the RTX 3090 overkill for gaming?

Yes, of course, this is overkill even for 4K gaming and 1080p gaming is just a joke for RTX 3090. As we have mentioned earlier, you don’t need this insane GPU unless you need a powerful workstation requiring extensive GPU power.

Final Verdict – Which is the Best RTX 3090 PC?

So these were my top recommendations for the best pre-built gaming PCs with the RTX 3090 GPU that you can buy without any second thought on your mind. I have tried to make a list as diversified as possible so that people with different requirements and budgets can also get a good PC. There are PCs with the best performance, the best value, the most affordable, and more. If we had to pick the best RTX 3090 gaming, we must have gone with Empowered PC Sentinel.

The compelling PC arrives with everything we were looking for in a perfect RTX 3090 PC, whether RAM, motherboard, storage or other components. This fascinating build attracts in every field. The concern is its high price, which is obvious with any gaming PC running the RTX 3090 GPU. The CUK Continuum Micro Gamer arrives with an 11th generation i9 CPU. Its refreshed hardware makes it a considerable choice. Moreover, if you are looking for something with a Ryzen chipset, CUK ROG Strix GA15DK is there to serve you, while the Omen 30L is the best value for money RTX 3090 gaming PC. That’s all!
