I'm planing to buy an A10-7870K, but I want to use the dual graphics feature of the APU, the main question here is: wich graphics cards are compatible with dual graphics.
Try it before you buy another gpu. It might be satisfactory as is.
In my own opinion I'd rather buy a really good discrete gpu (R9 something) instead of trying to get dual graphics working satisfactorily all the time.
but if you insist.
AMD Radeon Dual Graphics
R7 250 is the recommended Dua Graphics GPU for the A10-7870K.
