Thanks guys. I didn't know all the questions to ask. It has a 375 watt power supply and Intel motherboard. I gave the model # to Tiger Direct who recommended a GE force 6200 card. It only has pci slots that I found. Does the power supply sound big enough? There is cooling in the psu and processor. Should I add fans? Thanks again.
375 is enough, pretty much all lower end cards only need a minimum of 300 or less. So youll be fine.
