Looking to upgrade my graphics cards, wondering if I was to keep my motherboard the P6T Deluxe, if HD 7770 card would work in it? The cards are PCI-e 3.0 cards, but the P6T Deluxe is only a PCI-e 2.0. If they would work, would there be degredation?

Hi M..

Difficult to say if it would work.. AMD cards have problems on some boards.. but it should work...   There would be no perfromance difference from a 6000 series PCI-E 2.0 card.. assuming the amount of onboard memory is the same or greater.... but of course, the card could not provide PCI-E 3.0 bandwidth...

Do a bit of Googling...  P6T+HD7770 and see if you can find anyone else using that combination.

I have a P6X58-E PRO which has PCI-e 2.0 and am using a MSI HD7870 Hawk which is PCI-e 3.0 and it works like a champ. Apparently backwards compatability is no problem.
