A sound card should be added.
For me, I would ditch Windows and go with a Linux/GNU or *BSD distribution.
I'm planning on buying a Dell Inspiron 530. Cnet seemed to love it, because it's one of the top mainstream desktops. There's a deal going on until march 20 where you get $300 off an Ispiron desktop if you configure it over $999. I configured it for $1,009 so I could get it for just over $700. I'd like to see what you all say about it, especially the GRAPHICS CARD. I want to play games, but my budget is $750 so I'm going for the bang to buck ratio here. Thanks all!
