RX480 only running PCIe 2.0 instead of 3.0

Ok so just noticed in GPU-z that my RX480 only seems to be running in PCIe 2.0 instead of 3.0.

I click the little ? button to start the full power test and it only goes from 1.1 (idle/low power) to 2.0 and when playing games it's the same reading.

I'm running a Gigabyte z68xp ud3 mobo that has dual PCIe 3.0 x 16 slots so I know the MB supports it.

What could be causing this and how to fix it?
