Quick Answer
Yes — Half-Life: Alyx runs well on a R40,000 build, but it is VR-only and needs a locked 90Hz headset frame rate. A Ryzen 7 7800X3D paired with a RTX 4070 Ti SUPER or RX 7900 XT and 32GB DDR5-6000 drives 90-120 fps on a Quest link or PC VR headset without nausea-inducing dips.
The R40,000 build for Half-Life: Alyx
For a R38,000 to R45,000 budget at Evetech, the sensible core is a Ryzen 7 7800X3D, a RTX 4070 Ti SUPER or RX 7900 XT, 32GB DDR5-6000 and a 2TB Gen4 NVMe SSD on a 850W 80+ Gold, all inside a case with proper airflow. A high-end build uses the gaming-class 7800X3D and a 4070 Ti SUPER for 1440p maxed or entry 4K. The CPU pick matters because Half-Life: Alyx is CPU-bound in its busiest scenes.
Realistic frame rates on this configuration: 90 fps locked in VR 90Hz, and 90-120 fps in VR high res. Spend the bulk of the R40,000 band (R38,000 to R45,000) on the GPU and CPU, then keep the SSD, PSU and cooling honest — a cheap power supply is a false economy.
Settings and SA buying notes
Aim for High over Ultra first: on Half-Life: Alyx the jump from High to Ultra often costs 15-25 fps for a barely visible image change. A RTX 4070 Ti SUPER or RX 7900 XT card with 8GB of VRAM avoids texture stutter at 1440p / entry 4K. Downloading Half-Life: Alyx over SA fibre (Vumatel or Openserve, typically 50-200Mbps in most metros) takes well under an hour, so storage speed matters more than the download itself — a 2TB Gen4 NVMe SSD keeps load screens short.
NSFAS context: the R5,200 student allowance won't cover even an entry gaming PC, so students typically combine it with savings — the entry tier starts around R8,000 at Evetech. All parts above are stocked locally with local warranty support.
Where to spend more, where to save
The single best rand-per-frame upgrade at this budget is the GPU — stepping one tier up the card stack does more for Half-Life: Alyx than any other change. Don't overspend on RGB or a flagship CPU you won't saturate; a Ryzen 7 7800X3D is plenty for Half-Life: Alyx. Keep 32GB of RAM as the floor and a 2TB Gen4 NVMe SSD so future installs don't crowd you out.
FAQ
Do I need a VR headset for Half-Life: Alyx?
Yes — Half-Life: Alyx is VR-only. You'll need a PC VR headset or a Quest with a link cable; the R40,000 build above has the GPU headroom for a locked 90Hz without dropped frames.
Is 32GB enough RAM for Half-Life: Alyx?
The 32GB DDR5-6000 in this build is the comfortable sweet spot — modern background apps, a browser and the game together can use 12-14GB, so 16GB is the floor and 32GB is ideal at higher tiers.
Can I buy this build locally with warranty?
Yes — every component listed (Ryzen 7 7800X3D, RTX 4070 Ti SUPER or RX 7900 XT and the rest) is stocked at Evetech with local warranty and support, so there's no grey-import risk and RMA handling stays in South Africa.
