Suggested Graphics Cards For The Macintosh?

ntac writes "After the recent unveiling of the nVidia cards for the new line of G4's, my graphic design co-workers and I have been debating which card has the most bang for the buck. ATI seems to have burned a lot of bridges within the Mac community. Does the GeForce2 have the juice to replace the ATI Radeon? I've also noticed that Mac drivers are available for the 3dfx Voodoo cards - is this another viable option? As designers, we are looking for high performance in Photoshop, Illustrator, Quark, Flash, and Premiere. Any help would be greatly appreciated."
