SC, Geforce 4 MX440, came with the system.
Got the 9600Xt for $150 at NewEgg. They have really good prices. Its even better when the boss pays.

There was no way he'd shell for a 9800.

What's nice is if you get a DVI to VGA adapter (which I just happen to have

), you can have dual monitors! Which I don't happen to have at home

I'm hoping they arrive tomorrow.
By-the-by NewEgg also has the MS Intellimouse Explorer 4.0 for $23. Its not the wireless one, but man its sweet. Lighter and smoother than my IE 3.0 and has that sideways scroll. I really recommend it!
