I still have my original ATI x300se 128mb video card in my Dell 8400 computer. I'm running Windows XP with 4 Gigs ram and 3.2 cpu and am running two 22" monitors. I have a 350 watt power supply. I am not a gamer at all. I watch live streaming sports events, but sometimes the video can get pretty choppy or like slow motion, especially when I try to watch it in fullscreen. I don't have it stretched out onto both screens. If I just watch in the normal sized window than it is a lot better. What would be a good upgrade for me? Thank you, Bruce
