I built a high-end gaming PC in 2019 with an Intel Core i9-9900K, 32GB of DDR4-3200 memory, an RTX 2080 Super, and a 750W Corsair power supply. I mainly play sim racing on a single monitor and in VR, along with lighter games and the occasional demanding AAA title. Would it make more sense to save money by upgrading only to a newer 40- or 50-series graphics card, possibly replacing the power supply too, or should I start saving for an entirely new system?

I’d start with the graphics card rather than replacing the whole system. The 9900K is still a capable CPU and can support a much faster GPU, although the 8GB of VRAM on the 2080 Super may become a limitation, especially in VR or at higher resolutions. Look for a card with at least 16GB of memory, and only replace the power supply if the new card’s requirements call for it.
A complete rebuild would make sense if you were playing lots of new AAA or competitive games and wanted the highest possible frame rates, but your current system is still fairly balanced. A newer GPU should provide the biggest improvement for sim racing and VR. If you upgrade the rest later, you can reuse the case, storage, and possibly the power supply.
The 9900K is not automatically too old for a modern graphics card. It can handle cards around the RTX 4070 Super or RTX 3080 Ti level reasonably well, and even faster cards may work fine at higher resolutions where the GPU is doing most of the work. Upgrade the GPU first and see whether performance actually meets your needs before committing to a new PC.
There are also cheaper middle-ground options, such as moving to a newer processor while keeping DDR4, but that only makes sense if a GPU upgrade exposes a clear CPU limitation. Since your games are mostly light or GPU-heavy, buying the graphics card first is the safer and more cost-effective path.
If you do decide to build new, selling the old memory and graphics card can offset some of the cost. A modern gaming platform with DDR5 and a strong gaming-focused CPU would give you more headroom, but it’s difficult to justify while the 9900K still performs well. I’d wait until the current system fails to deliver the frame rates or VR smoothness you want.
That’s especially true for VR and higher-resolution racing setups, where the graphics card usually matters more than the processor. A CPU bottleneck is more noticeable at very high refresh rates or lower resolutions.
