First time build here, I am going with an amd cpu mostly for the multitasking capabilities, my question is are there pci express 3.0 amd mobos available, and if not how much of a performance loss will I see if I put it in this mobo?
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.
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.
