If it should last long, get a Geforce3 from one of the mayor players, like Creative 3D Blaster, Asus or the Gladiac cards.
Otherwise a good card is Asus Geforce MMX pro, cheaper not that a brawler, but gives you what you need for now and at least a year from now. But if you want to invest in a monster, any of the mayor NVIDIA supported Geforce 3 cards will do. Check the specs.. The more numbers the better!
