So I am getting ready to do a new build and I'm going to the core i5 3570. If I do the non-K version should I get a z77 or h77? And if my primary focus is gaming should I just go ahead and go to the K. I'm not sure if I plan to over clock but i am considering it if it will extend the lifetime (before a new upgrade) of my build. Or should I just go to the haswell? If so go to Z87?
