I have the same model. I thought a new Wally world PC would be great and I game alot. I bought the sapphire HD7750. It's pretty much plug and play. The card fit OK, I had to mess with the case a little, no big deal. Im not computer savvy so I got on here and read how to do it. I downloaded the most recent Catalyst 12.0. In all it took about an hour to get my PC going including 3 or 4 restarts. It was the first time I played on recommended settings and my jaw hit the floor. I was thinking where has this been my whole life.
