Fallout 4: ideal SA build at R15,000

An R15,000 SA build is the ideal balance for Fallout 4, pairing a fast CPU for the game's demanding city zones with a GPU strong enough for 1440p and moderate modding.

Quick Answer

At R15,000, a Ryzen 5 7600 with an RTX 4060, 16GB DDR5 and a 1TB NVMe SSD runs Fallout 4 at 1440p 90-120 fps in the open world and 60-90 fps in downtown Boston, with room for a moderate mod list.

The R15,000 Parts List

A Ryzen 5 7600 (around R4,000), an RTX 4060 (R6,500), 16GB DDR5, a 1TB Gen4 NVMe SSD, a B650 board and a 600W PSU fit inside R15,000. The modern CPU is the key part for Fallout 4, whose engine bottlenecks weak chips in cluttered city areas.

Fallout 4 Performance

Expect 1080p Ultra at 120-144 fps and 1440p Ultra at 90-120 fps outside the city, dropping to a steady 60-90 fps in downtown Boston where the CPU works hardest. A moderate mod list with 2K textures stays in the same range; very heavy 4K ENB loads need more VRAM and RAM.

Getting The Best Experience

Keep Fallout 4 on the NVMe SSD for fast loading, cap the frame rate around 120 fps to avoid the physics quirks the engine shows at very high frame rates, and use a mod manager for a clean load order. The RTX 4060's 8GB VRAM comfortably handles 2K texture packs. For storage, keep Fallout 4 and its mods on the 1TB NVMe SSD; the Creation Engine streams cells constantly, so a fast drive cuts the brief stutters that appear when crossing into new areas on a slower mechanical disk.

FAQ

What FPS does Fallout 4 hit on a R15,000 build?

Around 90-120 fps at 1440p in the open world and 60-90 fps in downtown Boston, where the game becomes CPU-limited on the Ryzen 5 7600.

Is R15,000 enough for modded Fallout 4?

Yes for a moderate mod list with 2K textures. Very heavy 4K ENB loads benefit from 32GB RAM and an RTX 4070, a step above this budget.

Should I cap Fallout 4's frame rate?

Yes, around 120 fps. The Creation Engine shows physics quirks at very high frame rates, so a cap keeps the game stable.
