GTX 670 SLI 8x/8x PCI Express 2.0 bottleneck?

[jjtober1]

Hi I am just curious what kind of bottleneck/performance drop-off you would see running a pair of 670's in SLI in 8x/8x with a 2500k @~4.8ghz. Can anyone point to me some benchies (680 benchmarks would be great if there are some) or something with a sandy bridge in 8x/8x, a Z68 or P67 board? I could not find any, thanks.

I think it will be fine
