What processor/motherboard combo with 570 gtx

[csorrentini]

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

and while im at it i currently have ep45-ud3p motherboard and a q6600 OC to 3.4. would it make a big difference going i3/i5/i7 with new board or would a qx9650 work just as well
