Do you "need" overclocking? No, nobody needs it, and the 7700k stock can eat up any AAA title no problem. But if you have a 7700k you might as well at least have a board that you can overclock with. However Overclocking and budget aren't always the best idea. When it comes to budget OC boards, the ASUS Z270 Prime is a good choice. But make sure you buy a good cooler (like the Cryorig H7) if you want to do this.
