Today's dual GPU's don't even use more than half of PCI-Express 2.0 bandwidth yet.

Honestly don't worry about it your card can't fully saturate a PCIE 2.0 or PCIE 3.0 slot. I remeber some site did a benchmark test pci 2.0 vs 3.0 and there was 1 FPS difference at most.

contact the mb vendor. on the newer z77 mb the pci mutiplexer chip is not the same on the x79 mb.
PLX PEX 8747 chip

if your mb has the n200 chipset it may be older chipset and cant do 3.0 or there a defect in your chipset.
