Quad-core necessary for sli

[phantomtrooper]

Im running an e8400 with a 9800gtx right now on a 750i mobo and Im looking to upgrade my graphics card for Crysis. I wanna know if my cpu can handle two gtx 275s without being a bottleneck, or if i should upgrade to a quad-core. most of the charts ive seen dont really show much performance gain in gaming even when going to a core i7, but i wanna find out from people who really have the machines.

OC ur comp to 3.4-3.6 and you should be ok.
E8400 is still fairly powerful
