I think it should show x16 2.0. Not sure about this. Did you use the pcie connector near the cpu? The other ones are x8 I think. Will check later. Here is the response from gigabyte So, run from this platform before it will have real limitations. They wont fix the problem. You are locked at pci-e 2.0 x8 or 2.0 x16 at best (like sandy bridge). Crossfire and anything beyond vega will probably suffer performance drop.
