im trying to build my first pc for editing all the footage from my japan trip and im so lost. i have like $1500 for the whole thing and i heard the gpu is the most important part for 4k but then someone told me the processor matters more?? i dont even know what a gpu actually does lol.

i keep seeing stuff about vram and like 3060 vs 4070 but the numbers are just confusing me. i just want my gopro 4k clips to not lag like crazy when i try to cut them together. is there one thats like the gold standard for this year that wont break my bank? sorry if this is a total noob question...
