Quick Answer
No at 1440p and 4K - the Ryzen 5 9600X can feed the RTX 5090 well, though very high-refresh 1080p play may hit a CPU ceiling first. Use about 110-150 fps at 1440p High with upscaling enabled as a practical planning target, then confirm with the same mission, area or benchmark-style run. For South African buyers, the CPU-and-GPU tier sits roughly around R70,000 to R95,000 depending on stock, cooler and board choice.
Bottleneck Verdict
The Ryzen 5 9600X has 6 fast Zen 5 cores and enough gaming headroom for Black Myth: Wukong. If the RTX 5090 is sitting near full use at 1440p, the graphics card is doing the hard work and a CPU upgrade is not the fix. If GPU use is low while one CPU thread is pinned, check background apps, BIOS settings and memory speed before replacing parts.
Wukong is shader-heavy, so the graphics card and upscaling choice matter more than extra CPU cores. Treat 1% lows as seriously as average fps: a clean 90 fps average with stable frame pacing feels better than a spiky 130 fps result on a busy Cape Town or Joburg evening session.
FPS And Settings Targets
Start at 1440p High with upscaling enabled, keep textures within VRAM limits, and only raise ray tracing or heavy post-processing when the frame-time graph stays clean. With this pairing, Black Myth: Wukong should land around about 110-150 fps; at 4K, expect the RTX 5090 to matter more, while at 1080p high refresh the CPU can show up sooner.
For competitive or action-heavy play, match the target to the screen: 60Hz is easy, 144Hz needs cleaner lows, and 240Hz is only worth chasing if the game supports it properly. South African fibre players should also separate network delay from hardware stutter before blaming the PC.
SA Build Notes
A sensible SA build around this pairing is 32GB DDR5-6000 memory, a 1TB NVMe SSD, and a B650 board such as MSI B650 Tomahawk WiFi or MSI B650-A PRO WiFi. Use a quality 1000W PSU for the RTX 5090, leave room for case airflow, and keep the game on NVMe storage so shader or traversal stutter is less likely to be mistaken for a bottleneck.
The RTX 5090 only makes sense with a premium display and a strong case/PSU plan; otherwise a lower GPU tier will often feel similar in this specific game. A broad Evetech shortlist should compare the GPU, PSU, monitor and case together, because the best value is often the complete platform rather than one headline part.
FAQ
Should I upgrade from the Ryzen 5 9600X for Black Myth: Wukong?
No, not for this pairing at 1440p. Upgrade the CPU only if repeated testing shows low GPU use, high CPU thread pressure and poor 1% lows after memory, drivers and background apps are already clean.
Is the RTX 5090 too much for Black Myth: Wukong?
No, it is a sensible high-performance GPU tier for this title when paired with the right monitor. The better SA buying decision is to match the card to your full game list, not only to one title.
What monitor should I pair with this build?
Choose a 4K 144Hz or 1440p 240Hz display before spending more on internal parts. A weaker monitor hides the benefit of the Ryzen 5 9600X and RTX 5090, while a good adaptive-sync screen makes frame pacing easier to notice.
