Hey guys. I'm almost done planning my new build, but I'm just not sure on the motherboard. Should I get a Big Bang Z77 Mpower by MSI or a Z77 OC Formula by ASRock? They're the same in price ($10 difference) and the ASRock one is an E-ATX board, but that's OK since I have a HAF X. I will run 2 cards SLI or Crossfire (don't know if 670 or 7970, help on this would be nice too).
Thanks.
