So i checked in the bios and it shows that my 7970 is hooked into a pcie. 3.0 slot. Also next to that slot on the board, it says pcie 3.0, so im fairly certain its plugged into a 3.0 slot. But i was looking through Catalyst Control Ceneter, clicked on the information tab, and then clicked hardware and saw this
Graphics Bus Capability PCI Express 2.0
Maximum Bus Setting PCI Express 2.0 x4
Is this normal? If not, what could be the problem?
