The Geforce 3 ti200 is an underclocked version of Geforce3, which actually has more potential than said card, since you can overclock most of the to200's to ti500 spec.
You can see here, that the ti200 is performing alot better than a geforce3 card when tweaked properly. It's the thing to do.

GF3 ti200 is cheap, it kicks ass, and will rock your Voodoo5 5500 be sure of that : )
With an amd XP1600+ processor you'd be running at 1280x1024, 32bit, with max settings, at 70-80 fps, sometimes up to 120 fps, especially on multiplayer maps, which is pretty nice.
