Key features of this Xidax X6 Onami Black RTX 5090 gaming PC

Ryzen 7 9800X3D processor for high fps gaming with low frame latency

This PC features the impressive Ryzen 7 9800X3D, which is one of the best CPUs for gaming on the market right now, and a very strong pick for the RTX 5090, if you’re after high framerates with very low frame latency. It boasts a 3D V-cache, which is specifically designed to store more data for quicker access and, when combined with its 5.2GHz boost clock speed, is very well-suited for high fps, super-smooth gaming at 4K. It has a relatively modest core and thread count of 8 and 16, which is enough for streaming and multitasking, alongside video editing and 3D work, but this CPU is really more of a gaming-first option. I’d suggest looking at processors like the Ryzen 9 9950X3D for something that offers great content creation and workstation capabilities. Be sure to check out our full Ryzen 7 9800X3D review here for more details.

RTX 5090 graphics card for top-tier gaming and content creation performance

This build packs the powerhouse RTX 5090, which is the best graphics card for gaming you can get at the moment. It’s an absolute unit built on Nvidia’s Blackwell Architecture, and boasts 4th-gen ray tracing cores, 5th-gen tensor cores, a massive 32GB of GDDR7 VRAM, a whopping 21,760 CUDA cores, and a large 512-bit bus. It’s a beast of a graphics card that can make short work out of 4K at ultra settings with ray tracing in even the most demanding AAA games. With content creation workflows, it’s incredibly fast in applications like Blender, allowing for superior viewpoint performance, quicker rendering, and better handling of very complex 3D scenes. For video editing, you’ve got 9th-gen Nvidia Encoders, which allow for much faster export times and better performance in tasks like color correction and real-time AI-driven tools. Read our RTX 5090 review for a deeper dive.

64GB of DDR5 RAM for powerhouse gaming and workstation capabilities

This build features a massive 64GB of DDR5 RAM, which makes it more than just a high-end gaming build, but something with extreme workstation capabilities, too. More RAM is essential if you’re working with huge files in applications like Blender and Premiere Pro, and with gaming, it’s going to help with reducing micro stutters in open-world games, and when you’re running multiple applications while gaming, too.

2TB storage for large gaming libraries

When it comes to storage, 2TB is ideal for those who want to have enough room for larger gaming collections, and don’t fancy constantly managing it to ensure there’s enough room for other files. It’s an expensive PC regardless, but one of the best ways to shave off some cash is to opt for a 2TB SSD instead of the frankly overkill 4TB options found in some of these high-end builds. We’ll take that as a win.

Things to consider

If you’re going for an RTX 5090 build, it’s not so much about saving cash, in many cases, but what your primary usage of it is going to be, and how well the components align to that usage. As mentioned, if you’re going to be splitting time between gaming and heavy content creation, then it may be worth investing in a higher core count CPU like the Ryzen 9 9950X3D. This is a beast with a huge core and thread count (16 and 32), 5.7GHz boost clock speed, and massive 128MB L3 cache. This is going to be essentially the best you can get if you’re looking for all-around performance. I found this Skytech prebuild for just under $6000, which could be of interest, at Newegg.
