Although an upgraded video card may be able to fit in this machine (not sure if it has an AGP slot or not) it is likely that the power supply might need an upgrade to be able to handle it properly. It isn't uncommon for prefab machines like dell, gateway, compaq, etc to have really skimpy power supplies (like 250W type of thing). Also, if you do upgrade the vid card AND the power supply isn't beefy enough, check with dell first to make sure if this is one of their proprietary power supply / mainboard things. Wouldn't want to stick in some good normal power supply and maybe damage it and or the mainboard hehe. Good luck.
