Not much to say about this, actually. APU processors from AMD do a fine job in using those processors as graphics cards too, but they are weak. You may use a R7 270x in dual mode with the APU, but it won’t help too much.
The answer is always: dedicated graphics card. This is why I like the FX line of processors. They have to crunch numbers and a dedicated graphics card will handle the video games as they should. Separation of power in a gaming pc, bro.
