2 * nVidia sli cards...mmmm FAST!
Ouch. Yeah it's SLI, but they are using the 6800LE. That's a horrid choice.
You'd really need to spend 200-300$ for 3D-card if you want to play games that were done 2004-2005. Sad but true.
Can't argue there... 900 for a complete system just isn't going to get you much unless you build it yourself.
