Table of Contents
We came across the Corsair Vengeance i8300 gaming PC on sale on Amazon with its lowest price ever in 30 days. This extreme performance gaming PC features the flagship RTX 5090 and the Core Ultra 9 285K, components that stand at the top of their respective lineups. With an 8% price cut, this beast will cost you $6,899.99, which isn’t cheap by any means.
So, we won’t recommend this prebuilt PC for casual and everyday use, but for extreme multitasking, this should be more than up for the job and get it done efficiently. It also has 64GB DDR5 RAM and 6TB of storage that should provide you with plenty of storage for a long time. That being said, it is one of the best gaming PCs we’ve seen and is certainly worth checking out.

What this gaming PC brings to the table
Core Ultra 9 285K
In our Core Ultra 9 285K review, we tested this 24-core and thread performance beast with various tests, and it performed exceptionally. It had outstanding performance in multi-core tests and even outperformed its competitor and predecessor; however, it gaming performance wasn’t the best. That being said, with the RTX 5090 at your disposal, you shouldn’t have to worry about it being held back by this processor.

RTX 5090
Here at PC Guide, we’ve reviewed the ASUS Astral RTX 5090 BTF OC and the MSI Suprim RTX 5090 SOC, so we are well aware of what the current best graphics card on the planet is capable of. There is no title or productive task that gives it any trouble, and it should be an excellent addition for content creators, data scientists, and other professionals who require nuclear-level firepower.
While it doesn’t need AI upscaling to run games at native 4K, when DLSS 5 releases, it should take the gaming performance of this GPU to a level never before seen. Here is how dominating its performance is:

Other components
Besides the CPU and the GPU, this gaming PC features the Dominator Titanium RGB 64GB DDR5 RAM, which we’ve also reviewed in-house. You can check out its performance in depth in our review. The combination of the 4TB and 2TB SSDs is also great, as that should provide plenty of space for the OS, games, applications, project files, and media.
Since the 285K is a flagship processor, you can also overclock it; it is cooled by the iCUE Link Titan 240 RX RGB liquid CPU cooler. This should ensure it doesn’t overheat and tank the performance. Overall, each and every aspect of this gaming PC is outstanding, and if you have the finances to score it, we would recommend it.
