Eventually also replace the GPU if you ever play some "modern" badly coded games, RTX 3060 is good but its starting to show its age, you should be able to use it for a few years more though.
Surge protectors arent that important and they are mostly needed in places with lots of electrical problems.
And cheap ones suck and are a bit dangerous.
When picking up a UPS just be sure its "Sinewave" and not fake sinewave because audio equipment hates "Square" sinewave.
