Hi Margaret, AGP is waaay faster than PCI. Since your system has an AGP slot, stick with that. For more information on the differences, see: http://en.wikipedia.org/wiki/Accelerated_Graphics_Port#Advantages_over_PCI I have the Radeon 9800 Pro in my G4 Sawtooth. It is a solid, dependable card. An excellent choice, I would say. Is there some reason you don't want to upgrade to 10.4.11? It has lots of bugfixes, plus you can download the latest security updates.
