I'm trying to figure out a new graphics card to buy to replace my current geforce 7600GS. I was looking into possible options before quickly discovering that my lackluster 300W power source could be a problem. The comp is the Gateway GT5412, I have only added memory to 4GB and the current video card. Is there any cards that you could recommend that would run well with my current PSU. Would obviously want an improvement in graphics for my games (nothing heavy just Rainbow 6: Vegas, CS-Source, etc.), HDMI output, and increased resolution. Any help would be greatly appreciated.
