Quick Answer

A R20,000 PC runs Fallout 4 maxed at 1440p above 100fps and handles heavy 4K texture and overhaul mods with ease. A Ryzen 5 7600 with an RTX 4060 Ti or RX 7600, 16-32GB DDR5 and a 1TB NVMe is the sweet spot, with the strong CPU keeping Fallout 4's notoriously demanding downtown Boston smooth.

Where The R20,000 Goes For Fallout 4

Fallout 4 rewards CPU strength and fast storage more than raw GPU horsepower, since its engine is single-thread heavy and load-bound. A Ryzen 5 7600 keeps downtown Boston above 90fps where lesser chips stutter, while an RTX 4060 Ti 8GB or RX 7600 drives 1440p Ultra plus mods. 32GB DDR5 is worth it if you plan a large mod list.

Performance Maxed And Modded

At 1440p Ultra this build holds above 100fps in open areas and a smooth 90fps+ in dense city scenes. With heavy 4K texture packs and overhaul mods at 1440p, it stays above 60fps - the extra VRAM and 32GB RAM absorbing the load. The fast NVMe also tames Fallout 4's long loading screens, a real quality-of-life win in this engine.

Storage, Stock And Buying In SA

A 1TB Gen4 NVMe is the practical minimum once mods are involved, both for capacity and load times. Confirm the live config before ordering and check the RAM kit is dual-channel. SA metro buyers can usually collect same-day, which is convenient for setting up a big mod list.

FAQ

What FPS does Fallout 4 get on a R20,000 PC?

Above 100fps at 1440p Ultra in open areas, and a smooth 90fps+ even in downtown Boston, the engine's hardest test. Heavy mods drop that toward 60fps, which the 8GB+ VRAM and 32GB RAM keep stable.

Is R20,000 too much for Fallout 4?

It is generous for the base game but ideal for a heavily modded 1440p experience and a future-proof all-rounder. If you run large 4K texture and overhaul lists, the headroom is well used; for vanilla only, a R10,000 build suffices.

Do Fallout 4 mods need more RAM?

Large 4K texture and overhaul mod lists benefit from 32GB. The base game runs fine on 16GB, but a serious mod setup streams more data and stays smoother with the extra memory at this budget.

For a modded Fallout 4 rig at Evetech, prioritise a strong CPU and a 1TB NVMe - they fix the engine's city-stutter and long load screens better than a bigger GPU would.
