Upgrading PC for mining

[Regolin542]

Hello, so i have a 2 quick questions. Can I buy e.g amd rx 560 and r9 290x and will it work with good enough psu, and is rx 460 and rx 560 the same card and will work with my rx 560(i'm choosing these cards bcs they are quite cheap in poland)

Those cards is not worth mining, too low hash rate for the power used. ow as far as mixing differnt GPU's on same computer. Yes that will work but try to stay all AMD or ALL nvidia.
