Half-Life Alyx-ready gaming PC under R20,000 for SA buyers

Quick Answer

Quick answer: Half-Life Alyx is VR-only, so at R20,000 your priority is a GPU that can render two eye buffers at 90Hz. For smooth 90 fps per eye on a Quest 3 or Index, target an RTX 4060 Ti or RX 7700 XT minimum; an RTX 4070 keeps reprojection off at high settings.

The parts list that makes sense at R20,000

At R20,000, is the SA sweet spot for solid 1080p gaming. A sensible spec list:

• CPU: Ryzen 5 7600
• GPU: RTX 4060 8GB or RX 7600 8GB
• RAM: 16GB DDR5-6000
• Storage: 1TB NVMe SSD

VR is latency-sensitive, so pair the GPU with a Ryzen 5 7600 or 7700 to avoid frametime spikes. All of these parts are the kind of components currently stocked at Evetech, so you can match the rig to what is actually in stock rather than a wishlist.

Performance: the numbers that matter

Half-Life Alyx is a VR exclusive, so your GPU has to render two eye buffers at 90Hz+, not a flat screen. For smooth 90 fps per eye on a Quest 3 or Index, target an RTX 4060 Ti or RX 7700 XT minimum; an RTX 4070 keeps reprojection off at high settings.

In VR, holding 90 fps per eye is non-negotiable — drops below that cause reprojection and discomfort. Aim for a card that keeps headroom above 90 fps so motion stays clean during fast sequences.

Local context and where not to overspend

• Don't over-buy the GPU. Spend to the tier the game needs, then bank the rest toward your next upgrade.
• Get 32GB if the budget allows. DDR5-6000 dual-channel keeps frametimes flat and future-proofs you against newer releases for a small premium.
• SSD first, always. A 1TB NVMe SSD cuts load times and stutter far more than a marginal GPU bump; modern game installs of 80-120GB fill a 500GB drive fast.
• Buy a quality 650W-750W power supply. It protects the rest of the build and leaves room for a future GPU upgrade without a full swap.

FAQ

Do I need an expensive graphics card for Half-Life Alyx?

Yes — VR doubles the rendering load. Target an RTX 4060 Ti or RX 7700 XT as the floor so you hold 90 fps per eye and avoid reprojection during fast movement.

What frame rate will I get at R20,000?

For smooth 90 fps per eye on a Quest 3 or Index, target an RTX 4060 Ti or RX 7700 XT minimum; an RTX 4070 keeps reprojection off at high settings. Pair it with a matching high-refresh monitor to actually feel those frames.

Is R20,000 the right amount to spend for Half-Life Alyx?

Yes for a 1080p high-refresh build. R20,000 is the SA sweet spot for solid 1080p gaming. You can step the GPU up or down a tier to match exactly what is in stock at Evetech.
