Yep know issue, oddly in some cases USB 3.0 Turbo Disabling turns-off other PCIe slots. Damned if you and damned if you don't.

The issue is that the 'USB Turbo' Enabled ties into the GPU PCIe lanes to 'steal' additional bandwidth. IMO - GA simply need to quit doing this practice. I've seen 4-5 cases of this ranging up to the UD7's.

as you say GA simply need to quit doing this practice or alert user about this so the user don't Freak when see the bus width decrease from x16 to x8

Imagine the 1000's that don't look with GPU-z! At least you were smart enough to check.

I'm with you! :)
