I'm looking to purchase a new Graphics card for my computer. Here's the details about my PC: -Inspiron 531s -Windows Vista Basic -250 watt power supply I'm looking for a card that I can play games with high quality. I'm not sure what to get though. I talked to Geeksquad and they said the card I need has to be a slim-lined so it can fit properly. Could anyone reccomend the proper card and if I should upgrade my power supply? It needs to be in the price range of $0-$250 dollars. Thankyou in advance.
