Dear user, Intel i5 3470, Z68 or Z77 is recommended.The two core mainboards support overclocking, intelligent response, fast storage, and fast startup.Overfrequency and intelligent response are the requirements of game computers, which support cross fire of games.If you want to mix hard disks, you need the motherboard to support fast storage.H77 is OK, but overclocking is not supported. I hope it can help you
