if you are going 3x SLI or xfire than that board is great but since you picked a 620 watt PSU i don't think you are so save yourself some money and get a another great board like:ASRock 990FX Extreme3 $165.99
then use some of the savings to get a better cpu cooler to overclock with:COOLER MASTER Hyper 212 EVO $34.99
then maybe take the other $40 towards some insanely fast CL7 ram:
G.SKILL Ripjaws X Series 8GB $79.99
edit: naw forget the ram . .
