Are PCIe 3.0 x 16 Graphics cards compatible with PCIe 2.0 x 16 motherboard slots? If yes, what are the cons?
yes but it will only run in pcie 2.0 which means half the bandwidth.
Is this resolved as the answers given should resolve this matter, you should have no problem what else do you need.
yes it is
Yes. The PCIe is compatible both ways. YOu can use a GPU with 3.0 on a 2.0 MoBo, and you can use a GPU with 2.0 on a MoBo with 3.0. I belive it goes for 1.0 as well.
yes, gpus with pci-e 3.0 are backward compatible with pci-e 2.0 slots on motherboards. I'm using a 7850 pci-e 3.0 on a gigabyte ma-790fxt ud5p with "only" 2.0 pci-e with no problem! Maybe you loose only 0,5fps or 1 :)
Yes, gpus with PCIe 3.0 will work on motherboards with only PCIe 2.0. You won't see any difference...maybe 0,5-1fps lower...because the bus PCIe 2.0 is not limiting card already
it'll support bt your won't benefit the full potential of the Graphics card. that will create a bottleneck in your system.
Yes, it must be compatible.. But i never try..
i havent heard before that there is 3.0 haha good question anyway...
From the explanation of PCI it self, it says that PCI 3.0 is "backward compatible with existing PCIe implementations".
Yes, they are. They won't have access to PCIe 3.0 bandwidth, but I don't think that's an issue with any current video card.
