I currently have a reference model gtx670 (leadtek) and planing to upgrade my cpu to an i5 3570k and later on get a second gtx670 but im wondering if the i5 will bottleneck sli 670s, will I be better off getting a 3770k? or perhaps get a high overclock on the i5? ill probably be oc the i5 to around 4.2 - 4.5 anyway. Any help will be helpful.

thanks, Jamie

In short. No it will not.

Nope. In the benchmark's I've seen, they're nearly identical in terms of gaming performance. The only difference is the i7 is better for higher threaded applications like video rendering.

No, not even a little
