Quick Answer

Yes, Half-Life Alyx runs well on a R80,000 build, but VR is the deciding factor, not the game itself. Pair an RTX 4090-class flagship GPU with a Ryzen 9 9950X3D or an Intel Core i9-14900K and you will hold a stable 90Hz in VR with no reprojection; budget separately for a headset, which Evetech stocks alongside the PC. GPU strength matters more here than for any flat-screen title at this price.

Where each rand should go

For R80,000, the spec that gives the cleanest value is a Ryzen 9 9950X3D or an Intel Core i9-14900K, an RTX 4090-class flagship GPU, 64GB of DDR5-6000 at CL30, a 2TB Gen5 NVMe SSD plus a 4TB Gen4 drive and a 1000 to 1200W 80+ Gold or Platinum PSU. R80,000 is a halo build: the fastest gaming hardware currently stocked at Evetech, with headroom for 4K 144Hz and beyond. VR doubles the rendering workload, so the GPU is the single most important part of this build; prioritise it over a flashier CPU.

Frame rates and settings

In VR you are aiming for a stable 90Hz in VR with no reprojection; dropping below 90Hz triggers reprojection that you feel as judder. an RTX 4090-class flagship GPU clears that bar in Half-Life Alyx, which is well optimised, and leaves margin for heavier VR titles. Cabling, tracking space and a comfortable headset strap shape the experience as much as raw fps.

Buying it right in South Africa

Fibre on Vumatel, Openserve or Frogfoot helps with the initial download, but none of these games need a strong connection once installed. At this spend, do not let one eye-catching part unbalance the build; a flagship GPU starves on a weak PSU or thin cooling. Spend on quiet cooling and a roomy case, because you will notice that every day more than a few extra fps in Half-Life Alyx.

FAQ

What spec do I need for Half-Life Alyx at R80,000?

Aim for a Ryzen 9 9950X3D or an Intel Core i9-14900K paired with an RTX 4090-class flagship GPU, plus 64GB of DDR5-6000 at CL30. That combination hits a stable 90Hz in VR with no reprojection in Half-Life Alyx and stays balanced for newer titles.

Which GPU should I get for this build?

Within R80,000, an RTX 4090-class flagship GPU is the sensible pick; it has the VRAM and raw throughput for Half-Life Alyx and current releases. Match the PSU (a 1000 to 1200W 80+ Gold or Platinum PSU) and case airflow to it so it runs cool and quiet.

How long will a R80,000 PC stay relevant?

A flagship R80,000 build will run new AAA games maxed for roughly four to five years before a GPU refresh tempts you, and Half-Life Alyx will never be the thing that ages it.
