What processor/motherboard combo with 570 gtx

well as the post says im about to purchase a 570 gtx card and i decided im just going to upgrade my cpu and mobo as well. im trying to decide which processor/mobo combo would go well with this card and what im going to be using the system for. Im a gamer so i need good performance and alot of the MMOs i play are just as intense on the cpu as the vid card. i looked at a few threads about how the i3 is a crazy overclocker but i want longevity on the system as well (2ish years). Any help would be great im ripping my hair out trying to decide lol soooo many options out now
