Well, where would I look for one? I have 3 white PCI slots at the bottom lefthand corner of my Motherbord. This CPU was Top-Of-The-Line in 2004. Was that really so long ago???
I had a look at your PC specs here:
http://www.dealadeal.com/cart/select_item.cfm?cont=78583&view.htmAs you can see, the PC is defined as a "Media PC" - NOT a gaming PC. While everything else is good enough to run SSM2007, it is very weak on the 3D acceleration side, which is not necessary for movies, music etc. This PC is meant for music and movies, not serious 3D gaming.
The lack of expandability is unfortunately a trend that some brand name manufacturers have chosen to follow. In this case it seems you are quite stuck with what you have.
While your PC is great at playing movies and music, it is not really adequate to play 3D-intensive games. Sorry.
