Re:card recommendations..GF4ti4200 (Score 1)

The Geforce4ti4200 is the best performance/value on the market at the moment. 64M versions can be had for $160ish, 128M for $180ish (newegg.com is the place to buy, BTW). A lot of these cards ship with very fast memory and can be OC'd to near, and sometimes beyond, 4600 speeds (that's a good thing).
Linux drivers aren't great, but better than ATI at the moment (that ain't saying much).
