lol, I tought of midrange cards
and you can always ask parents, lol... but anyways...
I'm gonna assume you have AGP slot, PCI-E are cheaper anyways:
The
GeForce 5500 256MB is a great deal at US$54.99, but for some bucks more you can get a
GeForce 6600 at US$109, that will let you play most of the new games and not worry about upgrading for some time
Take a look at ATI's cards too, they have some good ones.
