GTX 680/770 on (PCI-E 2.0 v PCI-E 3.0)

I know different motherboards have different generations of PCI-E slots, but i want to buy a gtx 680 or 770. I was wondering would PCI-E 2.0 "bottleneck" the gpu? Would it run around 100% or would I have to get a motherboard with PCI-E 3.0?

My current cpu is a 15 3570k. Thanks for helping me :)

    You have a 3570K and all Z77 motherboards have Pcie 3.0. Also the difference between X16 2.0 and 3.0 is 0.4fps in BF3
