sure there is plenty of good cards now a days that can handle kotor.
Depending on your form factor:
AGP: there's still a bunch on newegg, but prolly the best you can get is a ATI HD 2400, or either a Geforce 5400 or a 6200

PCI-e: on the other hand there is TONS of decent to good cards, and of course will make KOTOR run like a champ:

if you got pci-e, then go ahead and get one, and maybe look into something that'll push your wallet a little more, but it would be worth it in the long run, because those cards above can handle (obviously) new(er) games for your system, granted that you have a decent amount of RAM and CPU speed (preferably at least a dual core now a days)
