Quick Answer
For Fallout 4 at R20,000, build around AMD Ryzen 5 7500F or Ryzen 5 7600 and GeForce RTX 4060 Ti or Radeon RX 7700 XT class GPU with 32GB DDR5 and a 1TB NVMe SSD. The honest target is 1440p Ultra around 75-100 fps, with exact results shaped by settings, patches and the monitor.
Core Spec For This Game
Start with AMD Ryzen 5 7500F or Ryzen 5 7600, GeForce RTX 4060 Ti or Radeon RX 7700 XT class GPU, 32GB DDR5 and a 1TB NVMe SSD. A broad SA parts split is CPU R3,000-R4,500, B650 board R2,500-R3,800, GPU R7,500-R10,500, 32GB DDR5 R1,800-R2,700, 1TB SSD R900-R1,500; use it to spot unbalanced listings where the GPU is weak but the case and lighting look expensive.
Fallout 4 is older, so the goal is stable 60 fps, quick loads and enough VRAM for texture packs. For South African buyers, a stocked Evetech configuration with a tested PSU and clean cable routing is often easier than chasing every part separately, especially when delivery goes outside major city centres.
Settings And FPS Target
Set the monitor goal before choosing extras. For this budget, the sensible pairing is a 144 Hz 1080p or 1440p monitor, and the performance target is 1440p Ultra around 75-100 fps.
SA Buyer Checks
Use clear Rands when comparing builds: R20,000 should buy the CPU, GPU, RAM and storage listed above before cosmetic upgrades. Exact live prices change, but a GPU that sits one tier too low will be visible every time the frame rate drops.
For deliveries around Johannesburg, Cape Town, Durban and regional towns, keep the order simple, confirm the GPU is secured for transport, and keep the packaging until the first full gaming session is complete. Also check that the SSD has room for Windows, launchers and at least 80GB to 150GB of game installs.
FAQ
What FPS should I expect in Fallout 4?
Use 1440p Ultra around 75-100 fps as the practical target for this budget. Lower shadows, RT and crowd density before cutting texture quality, because textures usually preserve the look of the game better.
Is GeForce RTX 4060 Ti or Radeon RX 7700 XT class GPU the right GPU tier?
Yes for this budget class. It gives a stronger frame-rate lift than spending the same money on premium case extras, while AMD Ryzen 5 7500F or Ryzen 5 7600 keeps frame pacing steady.
Is R20,000 too much for this game?
It is only too much when the game is older and you will not play newer titles. If the PC must also handle modern AAA games, streaming or a 1440p monitor, the extra spend is easier to justify.
