I have 2 GTX 670 4GB gpus - I am yet to install the second. I know that PCI 2.0 x16 wont be a problem, but when I have 2 graphics cards installed, my motherboard (MSI P67a-GD53) runs in x8/x8. Will this bottleneck the system??

Thanks in advance!

No, it should not. PCIe 2.0 is more then enough even for the highest end GPUs. PCIe 2.0 x8 will not bottleneck it either. Hope this helps.

No, PCIe 2.0 will not bottleneck. There is not that big a performance between 2.0 - 3.0 at least right now. maybe 1% -_-

No. You're only bottleneck might be for some GPU compute stuff like bitcoin mining, but then you would be using a Radeon card :p . Anyway you shouldn't worry about it as the difference from 8x/8x 2.0 and 3.0 is very small in gaming
