Hello I have a Dell XPS 410 with Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz, 4gb of ram, windows 7 64-bit OS, 375 watt PSU and a Nvidia 7900GS. I am looking to upgrade my video card to the best one my psu can handle. Just looking for a few ideas. One of my friends told me the GeForce 220 GT 1gb DDR3 was a good one. Any help would be appreciated. Thank you.
