Yeah, the G3 Blue & White towers all came with ATI Rage 128 GL cards. Note, however, that that doesn't mean that any given B&W G3
has that card. There were a pretty fair variety of aftermarket video cards for PCI Macs, and I've seen a handful of different ones in towers I've picked up.
If you want to know about the stock specs of a given Mac,
EveryMac is the place to look.
