Quick Answer

A R20,000 PC runs Half-Life Alyx at a rock-solid 90fps for VR with headroom for higher-resolution headsets. A Ryzen 5 7600 with an RTX 4060 Ti or RX 7700 XT and 16-32GB DDR5 is ideal - but Alyx is VR-only, so plan for a PC VR headset as a separate, essential purchase alongside the build.

Why VR Headroom Matters At R20,000

Alyx is exclusively a VR title, and higher-resolution headsets render far more pixels per eye, so extra GPU power pays off. At R20,000 a Ryzen 5 7600 with an RTX 4060 Ti 8GB or RX 7700 XT 12GB holds a stable 90fps even on sharper headsets, where a weaker card would force you to drop settings. The PC drives VR confidently; the headset is a separate must-have.

VR Performance And Comfort

VR requires a steady 90fps to stay comfortable, since the GPU renders two eye views simultaneously - effectively double the work of a flat screen. This build holds that target in Alyx on high settings, with room for supersampling on higher-resolution headsets for a sharper image. Stable frame timing matters more than peak fps in VR, and the RTX 4060 Ti delivers it.

Headset, Storage And SA Buying

Budget for a PC VR headset as a core line item - the full Alyx setup is the PC plus the headset together. Alyx installs around 50GB, so a 1TB NVMe is plenty. Confirm current stock on the GPU before ordering; SA metro buyers can usually collect the tower same-day.

FAQ

Is R20,000 enough for Half-Life Alyx in VR?

Yes for the PC, which runs Alyx at a stable 90fps with headroom for higher-resolution headsets. Remember that Alyx is VR-only, so you must add a PC VR headset, a separate purchase beyond the R20,000 tower.

Why does VR need more GPU power than normal gaming?

VR renders two separate views, one per eye, effectively doubling the GPU workload, and higher-resolution headsets add even more pixels. That is why a stronger card like the RTX 4060 Ti helps maintain the stable 90fps VR comfort requires.

Can I supersample Alyx on this build?

Yes. The RTX 4060 Ti or RX 7700 XT has enough headroom to supersample Alyx on many headsets for a sharper image while holding 90fps. That extra clarity is a real benefit of the R20,000 tier over a cheaper build.

For Half-Life Alyx at Evetech, budget the PC and a VR headset together - Alyx cannot run on a monitor, and a higher-resolution headset is where the R20,000 build's extra GPU power pays off.
