Just a heads up for other noobs like me. I have a temporary MB in at the moment. It's a Gigabyte Z77m-DH3. It advertises as being crossfire ready but it practise it isn't! lol. For a start the front panel usb, audio and power stand by ect are all in the way. And secondly the FPS boost is, erm, not much of a boost, if a boost at all. I'm actually considering taking the second card out so that I can have my usb and wot not back.
