So, I can't choose a CPU cuz when I look at i7 6700K it has 4-cores (quad-core) and idk if I have to buy i7 OR 9590. I also know that when I want 9590 or 8370 I have to have some water cooling. So I can't choose, wich is better ? Is CPU better when it has more cores or MHz ? Or is i7 just the best ?
