Quick Answer
A R30,000 Fallout 4 build centres on a Ryzen 7 7700 or 9600X and a RTX 5070 or RX 9060 XT, which max the game at 1440p high settings. Expect roughly 100-165fps depending on scene and settings. Add 32GB DDR5-6000 CL30, a 1TB-2TB Gen 4 NVMe, and a 750W ATX 3.1 PSU. Fallout 4's engine is CPU-bound in dense city areas and capped near 60fps unless you adjust the engine settings, so raw GPU power matters less than a fast CPU and a frame-cap fix.
The Core Components
For a R30,000 build aimed at 1440p high settings, the heart is the Ryzen 7 7700 or 9600X paired with the RTX 5070 or RX 9060 XT. The CPU drives frame rates in busy scenes while the GPU handles the resolution and settings. Fallout 4's engine is CPU-bound in dense city areas and capped near 60fps unless you adjust the engine settings, so raw GPU power matters less than a fast CPU and a frame-cap fix. This combination maxes Fallout 4 comfortably and leaves headroom for other current titles.
The Full Parts List
Round out the build with 32GB DDR5-6000 CL30, a 1TB-2TB Gen 4 NVMe for fast load times, and a 750W ATX 3.1 PSU sized with transient-spike headroom. Use a B650 motherboard on the AM5 platform so a future CPU upgrade is drop-in, and a mesh airflow case to keep temperatures sensible in warm SA rooms. All of these are stocked at Evetech.
Performance to Expect
In Fallout 4, this build targets roughly 100-165fps at 1440p high settings, varying with scene density and your exact settings. Fallout 4's engine is CPU-bound in dense city areas and capped near 60fps unless you adjust the engine settings, so raw GPU power matters less than a fast CPU and a frame-cap fix. Pair it with a monitor that matches: a 1080p or 1440p 165Hz panel lets you feel the frame rates, and capping just under the refresh smooths frame pacing.
FAQ
What GPU is best for Fallout 4 at this budget?
A RTX 5070 or RX 9060 XT is the right pick for a R30,000 build, maxing the game at 1440p high settings. It balances cost against the frame rates Fallout 4 actually needs rather than overspending on raw power.
How many FPS will this R30,000 build get in Fallout 4?
Roughly 100-165fps at 1440p high settings, depending on scene and settings. Fallout 4's engine is CPU-bound in dense city areas and capped near 60fps unless you adjust the engine settings, so raw GPU power matters less than a fast CPU and a frame-cap fix. Pair it with a 165Hz monitor to feel the high frame rates and cap just under the refresh for smooth pacing.
Can I upgrade this build later?
Yes. Building on a B650 AM5 board means you can later drop in a faster Ryzen CPU, and the 750W ATX 3.1 PSU leaves headroom for a GPU step up. Start here and upgrade the one part that matters most when ready.
Build on a B650 AM5 board so a future CPU upgrade is drop-in, and pair this R30,000 rig with a 165Hz monitor. Check current part prices on the components above at Evetech.
