Too late lol bought and installed a 5800x3d seeing MUCH more fps in all my games now with miles better lows, was an amazing upgrade i think, dont feel like i need to upgrade the gpu for a while now, was thinking of getting a 4070 at some point but not so sure nowDLSS renders your game at a lower resolution. The lower the resolution the more taxing it is on your CPU. By removing DLSS you're effectively increasing the render resolution (not ouput resolution). This is causing your GPU to work harder. If you don't gain any meaningful increase in FPS with DLSS enabled, you're best leaving it disabled.
You likely don't need a CPU upgrade at the moment. Yes, some of your games are CPU demanding, but at 1440p you'd get much more of a result from a better GPU. Some games will never hit 100% GPU utilisation due to software/engine restrictions and overheads. Online multiplayer shooters are renowned for this. So long as you're 90-100% then you'd still benefit from a GPU upgrade on those titles.
May wait for next series of cards, all depends if the itch gets too bad lol but the cpu did make a massive improvement
