Why under AMD Catalyst Control Center under hardware info it says, Graphics Bus Capability PCI Express 2.0 Maximum Bus Setting PCI Express 2.0 x16
I thought the card comes with the new PCIe Xpress version 3.0 ? I have a Gigabyte 990 FXA-UD3 Motherboard is that all the motherboard is capable of 2.0? Thanks for a response... Repo

There is no real performance difference between running in PCI-E 2.0 and 3.0 right now

Looking at your motherboard model, it seems that it has PCI-E 2.0 slots so that would probably be the reason

Yes, pcie 2.0 only starts becoming the issue at something like 7990 levels.

At this particular time boards with Amd chipsets dont have pci-e 3.0, the difference is negligible as where the difference between something like usb 2.0 and 3.0 is at times like 145% faster ha. So in other words dont sweat it as the bandwidth supplied by the current pci express lane is more than enough.
