No, the quadro 3 isn't out yet, but there is a new quadro 2 pro chipset out. Elsa makes a card based on it, the Gloria 3. And why the hell would you need a card like that for Autocad 2000??? Polaris is right, for programs like Unigraghics and Pro Engineer you need real power!
I have the honour to sit behind a P3 Xeon with 1MB cache, 1GB SD-RAM and an Elsa Gloria 2. That's a Pro Engineer workstation, and really needs that power. But autocad isn't neer that demanding, it isn't that powerful to.
