Hello, after looking at my friends "gaming" PC the other day I noticed he had a gtx 520 and an A8 AMD CPU (The one with 6550D) I noticed this after he told me he wanted to upgrade his video card. He has a 350W PSU which is probably a major downfall. Does anyone know what is required to run Dual Graphics with the A8 and maybe a 6570 or a 6670?
