WHat would you all say? In terms of 20% of the budget torwards the CPU, and such like that?
Depends on what you want to do with your pc, and what your budget is. If you have 1k in US dollars and want the best graphics performance then %30-50 of your budget ideally should be spent on a GPU, but like I said it depends on what you need it for and what your budget is.
building your own PC requires alot of research, and requires you to sort out your needs/what you're going to be using it for.
