DOOM Eternal does not need the most expensive PC on the shelf - it needs a balanced one.
Quick Answer
Yes - DOOM Eternal runs beautifully on a R40,000 build using RTX 4070 Ti Super and Ryzen 7 7800X3D. 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 850W PSU and a roomy case now so the next GPU drops in without a rebuild. DOOM Eternal rarely needs more than 32GB 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 R40,000 you can comfortably run 1440p ultra to entry 4K with 144fps+ at 1440p, while keeping 32GB DDR5 of headroom for background apps. Mid-range cards hit 144fps or more at 1440p with ease.
Where your rand goes
On a R40,000 build the sensible split is roughly half on the RTX 4070 Ti Super, a quarter on the Ryzen 7 7800X3D and the rest on 32GB DDR5, a 850W PSU and the case. Skip flashy extras until the core is locked.
SA verdict
If your R40,000 budget is fixed, lock the RTX 4070 Ti Super and Ryzen 7 7800X3D 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.
FAQ

Pro Tip
If two DOOM Eternal build options are close, choose the one with the stronger CPU or more RAM; the GPU is the easiest part to swap later.
