So, I have an Asus P5QPL-AM Mobo that has a PCIe Express 2.0 x16 slot. Good graphic cards that use that kind of slot are really expensive, at least where I live. I want to buy a GTX 560 Ti and I can find way better and cheaper cards than this one at like half the price. Unfortunately, most of them need PCi Express 3.0 x16 slots. My question is, is it possible to use a PCIe Express 3.0 x16 intended card with a mobo that has a 2.0 x16 slot? If yes, any compatibility issues, since the 3.0 ones are newer.
