I currently have a Dell Inspiron 1545 with an Intel Core 2 Duo processor with 2.0 ghz processor speed. It has 4 GB ram and 320 GB hard drive. But the problem is the graphics card. It has an Intel Media Accelerater 4500 graphics card. I am looking to upgrade to something that will play the sims 2 a little better. Can you give me some choices and a link on where to actually buy them. I am looking at the 100 to 150 price range
