I am such a believer in NVidia Gforce cards. I have a 64mb MX400 and a 128mb 5200 and they're both still chuggin' along like pros. About 3 and 1 year old, respectively.
If you are heavily into gaming then you may well know more about vid cards than most of us on the board as if you are not reading about the latest vid card each week...you are left behind. I just upgraded to a GeForce 5200 & it chokes at Doom III at 640 but playable...just.
