Its got an AGP slot on the board, & I was wondering what I could put in it to give it a bit more oomph in the graphics department.
A PCI graphics card has throughput of 1/2 AGP. The slowest Mac AGP slot is AGP x2, so minimally a the slowest AGP card has 4 times the throughput of your PCI card, and perhaps 8 times if you have a G4 with AGP x4 slot.
You aren't getting any Quartz Extreme or Core Image acceleration with your Radeon 9200 PCI, although you can enable Quartz Extreme acceleration with PCI Extreme 3.1 available at MacUpdate. It works with 10.4.11.
Many 8x AGP cards need to be slightly modified by taping pins 3 & 11 to work in older G4 PowerMacs. If you're upgrading, getting a card that supports Core Image/Core Graphics would be best. Here is a list of compatible cards for all the G4 models, and another page on how to modify pins 3 & 11 for the cards that need modification:
