Wouldn't the Gigabyte mobo be better than the AsRock? I am planning to overclock my i5 2500k, and also crossfire x2 6950. The Gigabyte is x16 and x8 when Crossfire x2, and the AsRock is dual x8 when crossfire. I understand that the AsRock is PCI-E 3.0 but I don't plan to change my CPU anytime soon so which would be the best bet. I already got the AsRock for $120. Should I return for the Gigabyte which is $101? Thanks.
