Ok so right now my motherboard is an h170 pro gaming and I have an i5 6660k. Now, is it worth it to upgrade to an i7 7770? or an i7 7770k? because my motherboard doesn't support OC. But then I have to spend like 200$ on a new motherboard and another 400$ on a new cpu. I'm thinking about upgrading to an i7 7770k. to increase FPS in games that are CPU intensive. Do you think it's worth the upgrade to an i5 6660k from an i7 7770k because I heard if you get the k version you get more clock speeds?
