That Rage128 card isnt actually bad for what it's worth... I still use them in my G3 and G4 where they were stock items and video performance is quite adequate even under OSX. That said, if you wanted to grab a spice weasel and take things up a notch (BAM!!) you can get a Radeon 7000 or 9000 PCI Mac Edition card and and sqeauze every last bit of performance ya can out of it. The 9000 is available up to i believe a 128Mb model. Ive run the 32Mb 7000 however in a G3 and even that performs very nicely!
