Hello. I have an ASUS M4A89GTD Pro motherboard which is about 6 years old. I am interested in upgrading the video card to the RX 560 series. The motherboard manual indicates that it has a PCIe 2.0 x16 slot, but it looks like the RX560 uses PCIe 3.0 and I am not sure if the card is backward compatible to 2.0. How can I find out if this board is compatible with the newer video card?
