Thanks for your recommendations. I use this computer in my home movie theater and mainly just use it to stream movies from Netfilx, surf the net, etc. Not really used for gaming, but I like the last video card. The Radeon 4670 recommends a 400 watt power supply. Would the one I linked below work and would I need any other components other than the Radeon video card and this power supply? Thanks again for your time.
