whats your budget? i have the p8z77-v and its a full sized atx board, and you can do crossfire or sli with it, the p8z77-v pro is only a few bucks more and is a little better though
I reallu just want to know the cheapest boards that support my requirements. and a good quality board to. The only brands I have heard good about are asus gigabyte and a few asrock boards.
