My gaming PC is about eight years old, although it was close to high-end when I built it. It has an overclocked i7-9700K running at 4.7 GHz across all cores and a slightly overclocked MSI GTX 1080 Ti. If I replace the platform, I would probably need a new CPU, motherboard, RAM, and graphics card, while keeping the power supply and case. Memory and GPU prices are unusually high right now, so I'm wondering whether it makes more sense to wait. I know 1440p and 4K may be difficult in newer games, but my current system still manages roughly 75–130 FPS at medium settings in most titles. Anything below 75 FPS is very noticeable to me. Would upgrading only the graphics card be worthwhile, or should I replace the whole platform?

There is also a good argument for doing a partial platform upgrade now. Your existing parts still have some resale value, which can reduce the cost of a newer CPU and motherboard. Just remember that the 9700K uses DDR4, so you should verify memory compatibility before planning to reuse your RAM in a new build. If your current performance already meets your 75 FPS target, though, waiting is perfectly reasonable—there is no need to upgrade just because the system is old.
The simplest upgrade is probably the graphics card. The 1080 Ti is still capable, but it lacks newer features and is beginning to struggle in current games. A modern card could let you play at 1440p with high settings and around 75 FPS or more. Your 9700K may limit the card in some CPU-heavy games, but that does not make the upgrade pointless—you would still get a much better experience immediately.
Your processor is old, but its eight physical cores are still usable, especially at 1440p or 4K where the graphics card usually matters more. A complete rebuild is not essential unless you are chasing very high refresh rates or running into obvious CPU limits. Upgrade the GPU, monitor your frame rates and GPU usage, and replace the rest only when the CPU is clearly holding you back.
