Need some advice about a pci 3.0 card

There's no amd motherboard with pcie 3.0, any pcie 3.0 card is backwards compatible with previous pcie, since you have pcie 2.0 at 16x, there's no restrain from it, the card will perform at the maximum capability.
You're fine.

PCI express 3.0 is only available via Intel based motherboards from what I have seen. The GPU is backwards compatible with PCIe 2.0, it just won't run at the same speeds on an Intel based board.

What processor are you pairing with the mobo?

planning on going with this amd chip, I realize an intel would be better for the gaming I am wanting to do, but I also want to do alot of video editing with programs such as adobe after effects and sony vegas.

While the GPU may not run at "100%", it will provide good graphics for those purposes. It would be similar to buying a SATA III drive when you only have SATA II connections...

If you upgrade the computer later to a mobo that has PCIe 3.0 - you will be able to use it's full potential.

I think you will be happy with the combo - I wouldn't be concerned about the PCIe 2.0 vs. 3.0....

That cpu is fine if you want to do editing.
What count most is the card, that cpu won't bottleneck the card.

Thank you for the advice I think I will move ahead with my planned build.
