A good this choice choice rewards matching the part to your room, your screen and your budget, not the spec sheet.
Quick Answer
For Fallout 4 around R100,000, build a flagship 4K rig: a Ryzen 9 9950X, an RTX 5090, 64GB DDR5 and a 2TB+ NVMe. That mix targets 4K ultra comfortably in Fallout 4. Spend any spare on the GPU first, then storage.
The core parts for Fallout 4
The RTX 5090 is the heart of this build and where most of R100,000 should go. Back it with the Ryzen 9 9950X so the card never waits, plus 64GB DDR5 for smooth multitasking and a 2TB+ NVMe for fast loads. Fallout 4 is well served by this balance, hitting 4K ultra.
Where to save and where to spend
Trim the case, fans and peripherals before touching the GPU or CPU. A R900 case with good airflow does the same job as a R2,000 one for gaming. Put any extra into a larger NVMe or a better GPU tier, since those move frame rates and load times most.
Power, cooling and SA climate
Size the PSU for the GPU with headroom: a quality 650W to 850W unit suits this tier. Add front intake fans and a mesh panel because SA rooms run warm in summer. A good air cooler keeps the CPU calm without an AIO at this level.

FAQ
What can I play with a R100,000 build?
It targets 4K ultra, which covers Fallout 4 comfortably. Esports titles run far higher, and you can lift settings as you upgrade.
Should I spend more on the CPU or GPU?
The GPU, almost always for gaming. A balanced CPU like the Ryzen 9 9950X is enough; extra money in the graphics card buys more frames.
Is 64GB DDR5 enough?
Yes for gaming today. It handles modern titles and background apps. Step up only if you do heavy creative work alongside play.
