I was about to buy the Nvidia GeForce 4MX for $65 at OWC. But then I saw this warning on OWC's page about it: OWC NOTE: Mac OS X 10.3 not supported in some configurations, at this time AGP "Sawtooth" Systems are confirmed as not functioning properly. Apple has a support page about this issue here ; hopefully more information will become available on this issue in the near future or rectified with a 10.3.x update. Since the card is not officially compatible with the Cube, I am afraid to buy it unless someone can confirm that the card will work with 10.3 in a Cube. Seth, I believe you were the first to install this card in a Cube....Have you upgraded to Panther yet? If so, is the 4MX working ok? Has anyone else installed this card in a Cube so far? Thanks, Mike
