just to clarify, with this board and ivybridge CPU and 2 graphics cards..

Both slots will run 8X, will they BOTH be PCIE 3.0 @ 8X ?

The PCIe channels are determined by the PCIe controller on the PCU these days. Which is why the X79 CPU's are able to run 40 lanes and the Ivy CPUs not.
To help us help you - please provide as much information about your system and the problem as possible.

Yes, I knew the lane restrictions, and that both slots would run at 8X but just was not sure they would both be PCIE 3.0 .

I finally got around to putting the 3770k in my main rig and both slots run 8X PCIE 3.0 so it's confirmed 🙂

and I think If I went Z77 with one of those fancy PLX switches I would even get 16X-16X 3.0 but gonna hold off for now.

Thanks for your help you two.
