As long as you get a motherboard with a pcie-x16 slot yes. You will be able to draw the power from the APU and the dedicated GPU for better performance.
Awesome thanks buying a build from amazon not too confident in building my own haha
In order to run dual-graphics with the A8-6600K (if that is your intent), the best partner for your APU is the Radeon HD6570 1GB DDR3. The faster your RAMs, the faster your frames.
You will need to set up individual game profiles (it's easy). Some games run dual-graphics great -- others, not so much. Simply set them up to run on the HD6570.
