Hello, I'm planning to buy A10-5800k and a 6670. I had read an article for the past month that cross-firing (Dual Graphics) the integrated graphics of the APU with the 6670 will give you a better performance overall, especially in games. But as I'm looking for reviews yesterday, a lot of people do not recommend of using the Dual Graphic feature. They say that when your planning to buy a discrete graphic card, just forget to buy the AMD APU's and buy an Intel. Is this really true? Please enlighten me as I don't have enough money to buy an Intel system. All I want is to play GTA IV (may'be V in the future), Sims 3, GW2, some photoshop and for everyday computing. I want to improve the performance of the APU as much as possible, if you don't recommend the Dual Graphics, will a 1866 RAM help? or 1600 mhz is more than enough?
