Plan a DOOM Eternal machine around the game's real demands, not the marketing on the box.

Quick Answer

Yes - DOOM Eternal runs beautifully on a R80,000 build using RTX 4090 and Ryzen 9 7950X3D. Mid-range cards hit 144fps or more at 1440p with ease, so you can aim for high frame rates rather than just scraping past minimum specs.

Upgrade room later

Buy a 1000W PSU and a roomy case now so the next GPU drops in without a rebuild. DOOM Eternal rarely needs more than 64GB DDR5, so RAM is the cheapest later top-up if you multitask.

What the game actually asks for

DOOM Eternal's id Tech 7 engine is famously well-optimised and Vulkan-fast. At R80,000 you can comfortably run 4K ultra max with 120-240fps at 4K, while keeping 64GB DDR5 of headroom for background apps. Mid-range cards hit 144fps or more at 1440p with ease.

Where your rand goes

On a R80,000 build the sensible split is roughly half on the RTX 4090, a quarter on the Ryzen 9 7950X3D and the rest on 64GB DDR5, a 1000W PSU and the case. Skip flashy extras until the core is locked.

The bottom line for SA buyers

If your R80,000 budget is fixed, lock the RTX 4090 and Ryzen 9 7950X3D first, then spend whatever is left on storage and a better PSU. Mid-range cards hit 144fps or more at 1440p with ease at sensible settings, so resist overspending on a GPU the game cannot use. The build that runs DOOM Eternal well today and takes one GPU upgrade later is the one most SA gamers should pick.
