The card in my primary box is a Nvidia GeForce 3 64mb DDR Pure ES (Enginering Sample, which means one of the original cards actually produced in the Nvidia Labs). So far im happy with it, though in the next year or so ill need an upgrade.
The card in my secondary box is a ATI Radeon 7000 64mb DDR. Its alright, but a very limited card. Not good for heavy gaming.
