To every one that said ATI sucks, I will gladly bet you that a Radeon 9700Pro at 1600x1200 with 4xAA and 16xAF your GeForce4 will get stomped on.
However I wouldn't look at the Radeon 9700 at that budget, unless all you really need is the box and not the monitor OS etc.
Audigy plain flat out sucks, go read [H]|F's soundcard forum and look around

you still need a OS mouse and keyboard. The LCD is damn expensive. If you got a CRT instead you could shave it down to 1k pretty easily...
