I have a Dell Dimension 3000 that came with an integrated video card of 128 so I bought an Nvidia GeForce FX 5200 256mb pci video card. I installed it and for some reason games play slower. I upgraded the power supply unit from 250w to a 400w and it helped with some lagging but game play seems to be worse. I tried rolling back the driver for the video card but that hasnt helped. What do you guys think I should do? Once again any insight is greatly appreciated. I thank all of you for your help.
