With my Tax money back i'm going to upgrade my graphics card. Since I run an AMD processor would an AMD Radeon graphics card work better for me than an Nvidia? Would I have compatibility issues with an Nvidia? My processor is AMD A10, with attached Radeon 6700 graphics (APU), but I have 1 PCIe X 16 port and 1 mini PCIe available. Though I'll probably need to save the mini port to add some kind of cooling system beyond the fan that came with my tower.
