I got my 4670k with my gigabyte z87 hd3 first of all what is your opinion about this motherboard or what your experience with it if you have/had one secondly how much can i push my cpu with this board?
Depends more on your individual chip, with that mobo, I'd say 4.5-4.6 is possible if the chip can OC that high, also depends on your OC abilities (and maybe more, your patience )......All 4670Ks are different, just depends on how good a chip you have:
