Well without knowing your location and exact computer model, I'm going to go with some general statements. Most models of the computer appear to have a PCI Express x16 slot, so just about any graphics card should be fine. If you're only doing web browsing and playing music, just get something cheap like this 6570 for $50 or even this 6450 for $40.
Edit: Even this 5450 should be fine (only $17 after rebate). Just find something cheap with an HDMI port to make things as easy as possible. Go to the full post
