Re: Graphics card
Depends. I recently put one in a computer with 2gb ddr2 800 and an E5200, and could run Mirrors Edge (runs on the UT3 engine if you're unfamiliar with it) on low settings at around 40 fps on average. For gaming it's pretty low end, but you can get away with some stuff on it. For everyday wordprocessing and what not it's more than enough.
