Just in case anyone came back to this thread:
Decided to take the chance and buy a MSI G4 Ti4200 64MB VIVO from Newegg. It works great! I get 5000+ 3DMark right out of the box (double compared to the radeon aiw). Stable at AGP 1x, trying to get it to go to 2x but the 'enableirongate2x' registry mod doesn't seem to work. If anyone has suggestions I'd appreciate it. Thanks.
