Is there a reason why you are going down this path? Dual graphics setups are almost always more of a headache than an equally potent single chip solution. Between frame pacing and profiles and whatnot there's just a lot that can go wrong here. Is this a system from a vendor or are you building the system yourself? If you are rolling your own I would HIGHLY recommend a cheaper iGPU disabled Athlon chip (perhaps one with an unlocked multiplier) and putting that savings towards a more potent GPU. Better yet, this is a really bad time to build an AMD based system as a new platform will be replacing FM2+ in a matter of weeks and this platform will have far greater support in the future (1st gen Zen support will be a given in most cases) whereas FM2+ is a dead end. There's plenty of us here that would be more than willing to assist with a build as well. If you do need a system ASAP, I'd check out the for sale/for trade forum and grab a used combo as you'll get way more bang for the buck that way.
