I am building a gaming rig and while I know I may not NEED some monster mobo, a nicer upgrade wouldn't hurt. So I have been looking at the ASUS SABERTOOTH Z77 and now that the new ASRock OC Formula is out I was wondering how people think it will compare to the ASUS? Also will the OC Formula work with a standard ATX case? or would i need an E-ATX case? Are there other good standard ATX boards with at least 6 rear USB ports, 3 case fan headers and 2 CPU fan headers?
