Gaming performance was unsurprisingly better at 1440P when compared to 4K in the titles I tested (for full details watch our video review on YouTube) – Escape from Tarkov Arena was a particular highlight when running at 2560×1440 with maximum settings, as the game can sometimes struggle on even high end machines. Call of Duty Warzone ran at roughly the same level when testing at 1440p.
Moving up to 4K does see the framerates tumble – dropping significantly in Warzone. However, as the system has an RTX 5070, the use of DLSS 4 and multi frame generation are an option and do improve fps significantly, as can be seen in the screen capture from Cyberpunk 2077 below.

Escape from Tarkov: Arena (1440p)

Call of Duty: Warzone (1440p)

Call of Duty Warzone (4K Native)

Cyberpunk 2077 (4K Native)

Cyberpunk 2077 (4K – DLSS 4 Quality – MFG 4x)

The Elder Scrolls: Oblivion (4K – DLSS Quality, FG Auto)
Overall, the Onyx Pro desktop performed as expected and is much more suited to 1440p gaming, especially if playing competitive titles and targeting high framerates. However, it is still very capable of gaming at 4K, as long as you are willing to utilise DLSS and frame generation. If full rasterised gaming at 4K is your goal then you will need a little more grunt under the hood.

Pros:
- Very competitive pricing when compared to build a similar system.
- Solid 1440p gaming performance.
- Good 4K gaming performance when using DLSS and frame generation.

Cons:
- 5600MT/s CL40 memory could be better.

KitGuru says: The Onyx Pro is very well priced and offers good gaming performance with the latest features from Nvidia.
