I see on AMD's official website that to use their Dual Graphics capability, the "recommended" pairing for an AMD A-10 7850K Kaveri APU is an AMD R7 250 series graphics card.
Question: To take full advantage of AMD's Dual Graphics capability, does my graphics card absolutely have to be a R7 250? For example, can I pair my 7850K APU with a R9 series card? Or where can I find a more detailed Dual Graphics compatibility chart?
