Not a lot of people will recommend going the dual graphics option. AMD has all but fixed it. Some games still struggle with it, although a lot of the glaring issues are gone. That said, I think the performance is theoretically on par with one-another.
Personally, I would stick with the FM2+ platform, get the Athlon 760k, and put the money saved towards a Radeon R7 265. The gaming performance will be a magnitude level better.
How much money, overall, were you going to spend?
