I’ve been pretty much upgrading my own desktop PC regularly since the 90s (though I did buy a brand new one 6 years ago).
In my experience the upgrade that’s more likelly to improve it the cheapest is RAM, then a graphics card if you’re a gamer.
Upgrading the CPU has always been something that happens less often and also it doesn’t help that the CPU can only be upgrade up to a point without having to replace the motherboard (which then forces replacing the RAM and possibly even the PC box).
However there were two transition periods were the best upgrade by far was something else: the first was back in the day when hardware 3D accelerator boards were invented (Quake with a 3dfx was night and day compared to software rendering) and the other one was the transition for HDD to SSD, both being massive jumps in performance.
