I currently have an A8-5600K processor with a F2-A85-V PRO asus motherboard, and an asus geforce gtx 660. I am planning on returning either the mobo/APU or the GPU. Would you reccomend spending 70 dollars and upgrading my processor to a decent i5, or spending it on upgrading to a radeon 7950? I want to play games like battlefield, Arkham Origins, skyrim, far cry 3, guild wars, (basically very hard to run games) on at least high settings 1080p. Which would be the optimal setup? Please help.
