If you want to build a gaming rig get a EVGA 780i motherboard, I bought one in mid February and haven't had one problem with it yet. BIOS are good, it allows for good overclocking and I would recommend it. One of my friends has an ASUS P5Q and he says it hasn't had any problems since he bought it in November. So those are both two good motherboards.
ASUS P5Q- $150
EVGA 780i- $260
