There's too many. I want to go nvidia, because I've been very pleased by their products. I kinda want the 9800 gt, which looks crappy compared to mah 7950 gx2 but I don't really know. I just got a 22" widescreen monitor and now all of my games are laggy (Tf2, CS:S, etc.) when I play them, and it's quite annoying, seeing as they all were fine when I was running 2 monitors.
I are having trouble. Halp. :D
Edit: I sound like I don't have a loving clue about computers :o
