Quick Answer

At R80,000, an Evetech build around an RTX 4080 SUPER or RX 7900 XTX with a Ryzen 7 7800X3D or Ryzen 9 7900X and 32-64GB DDR5-6000 CL30 runs Doom Eternal at 200+ fps at 1440p Ultra Nightmare. That hits fast FPS performance well above what Doom Eternal demands, leaving headroom for newer AAA titles.

What this R80,000 build looks like

The core of a sensible R80,000 rig at Evetech is an RTX 4080 SUPER or RX 7900 XTX, paired with a Ryzen 7 7800X3D or Ryzen 9 7900X, 32-64GB DDR5-6000 CL30 and 2-4TB Gen4 NVMe SSD. Feed it with a 1000W 80+ Gold unit and a case with at least two intake fans. This combination targets no-compromise 4K Ultra and high-refresh 1440p, which comfortably covers Doom Eternal.

Getting the most out of Doom Eternal

Doom Eternal (2020, id Tech 7 (Vulkan)) renders vertical platforming arenas and demon hordes at high speed. Id Tech 7 is one of the best-optimised engines around and rarely CPU-limited below 144Hz. The one setting that moves frames most is Texture Pool Size and Shadow Quality — drop it a notch if you want more headroom — while Lens Distortion can stay on for negligible cost. Budget 4GB at 1080p, 8GB for Ultra Nightmare textures of VRAM for your target resolution.

Buying smart in South Africa

All parts here are stocked locally at Evetech with SA warranty support, which matters when you need an RMA turned around quickly. Spend first on the GPU and a quality power supply, then storage — an NVMe SSD removes the texture and level-load stutter you would feel on an old hard drive in Doom Eternal. Add fans before RGB; thermals decide whether your frames hold over a long session in a warm SA summer.

FAQ

Will a R80,000 build run Doom Eternal maxed out?

Yes. A R80,000 Evetech build around an RTX 4080 SUPER or RX 7900 XTX runs Doom Eternal at 200+ fps at 1440p Ultra Nightmare, which is at or above maxed settings for this game.

How much VRAM do I need for Doom Eternal?

Plan for 4GB at 1080p, 8GB for Ultra Nightmare textures. Doom Eternal is not the most VRAM-hungry game, but matching VRAM to your resolution keeps frame-times flat in busy scenes.

Will this build handle newer games too?

Yes. Sized for Doom Eternal, a build like this has clear headroom, so it will run most current AAA titles at high settings and stay relevant for a few years of new releases.
