Could someone please confirm for me that I have the G4 Sawtooth? Remember when Apple went from 400, 450, and 500 MHz models down to 350-450? Well, I got a 500 AFTER they went back to 500 mHz and before they went to dual processors, and I have an AGP video card (Radeon). I think this means I have the Sawtooth, but I'm not sure. Thanks in advance.
