My gaming PC is about 10 years old, although it was near the high end when I built it. It has an overclocked i7-9700K running at 4.7 GHz on all cores and an MSI Gaming GTX 1080 Ti with a mild overclock. If I upgrade the platform, I would probably need a new CPU, motherboard, RAM, and graphics card, while reusing my power supply and case. Memory and GPU prices are currently high, so I'm unsure whether it makes sense to buy now or wait. I know newer games at 1440p or 4K may be difficult, but I can still run most current titles at roughly 75–130 FPS on medium settings. Since anything below 75 FPS is very noticeable to me, would I be better off replacing only the graphics card for now, upgrading the whole system, or waiting?

Your processor is old, but it is still an eight-core CPU and remains usable for gaming, especially at 1440p where the graphics card does most of the work. If you are happy with your current frame rates, waiting is reasonable. However, prices could remain high or increase rather than fall, so there is no guarantee that delaying will save money. Buy when the performance improvement is worth the cost to you, rather than assuming the market will definitely improve.
There is also a case for doing a partial platform upgrade now. Your existing parts still have resale value, and depending on the platform you choose, some components—such as compatible DDR4 memory—may be reusable. A moderately priced CPU and motherboard paired with a current midrange GPU could bring a major improvement without immediately requiring a premium, cutting-edge build. Selling the old CPU, motherboard, and graphics card would reduce the total cost.
Since your PC is already several years old, reliability is another factor. A component failure could force you to buy everything quickly, leaving less opportunity to wait for sales or compare options. If you want better settings and 1440p performance now, upgrading the GPU first is the lowest-risk approach. If you are satisfied with medium settings and 75 FPS, keeping the system and saving money is still perfectly defensible.
The most straightforward upgrade is the graphics card. The GTX 1080 Ti is still capable, but it is showing its age in newer games and lacks newer features that many titles now use. A modern card could give you a much better 1440p experience immediately. Your i7-9700K may limit the card in some CPU-heavy games, but that does not make the upgrade pointless—you might get 100 FPS instead of 120–140 FPS, which is still a substantial improvement over the 1080 Ti.
