I've already heard that amd's APUs can utilize both integrated and dedicated graphics at the same time. What I'm wondering is if I can actually install an extra graphics card in addition to the already available igpu on this computer. If I can, I would like to hear suggestions for what graphics card i should install that's compatible. http://www.costco.com/HP-Pavilion-500z-Desktop-%7c-AMD-A10.product.100156529.html Never built or customized a computer before I just know about it
