Will there be compatibility problems on the motherboard with the PCI-E 2.0? I've heard many buyers of the RX 4** series are faced with problems of backwards compatibility, will there be the same problems with the RX 5** series? I have a processor Phenom II x4 965 (3,7 GHz) on socket AM3 and now I have an ASUS R7 360 OC-V2. I do not have the money for a full upgrade and until I get only a graphics card, namely RX 560. For this system it is quite suitable, if there are no problems with backwards compatibility. Or maybe I should buy another video card, but only exclusively from AMD in the same price range?
