King A,
For what you will be doing, there is an card older than the Radeon series that can handle those tasks. It the the ATI Rage 128 Orion. It has a 128-bit graphics processing unit (GPU) that is considerably more robust than the 64-bit GPU on your logic board, and has 16MB VRAM. I used one for a long time, including with Jag when one of my Radeons lost a cooling fan, and it is a very good card. Used price is probably in the US$15-35 range.
"Orion" was the name appended to the retail boxed version of that card. More common on the used/pulled market is its twin, the ATI Rage 128 Pro PCI model. It was factory-installed in B&W G3s and early G4s with PCI graphics. Be careful--there is also an AGP version of the Rage 128 Pro, so you have to make sure anything you order or bid for is PCI or you're out of luck.
Dave speaks highly of the original Radeon Mac Edition 32MB card, and I heartily concur. My RME was much more stable than my current 9200. The 9200 can cause OS9 graphics apps to crash, and is overkill for most things a Beige G3 can do. The only app I have that really uses the 9200 is my flight sim, which wants over 100MB VRAM at the settings I run.
This article shows the facts behind Dave's opinion of the Radeon ME 7000 compared to the original Radeon ME. Facts is facts--it is not the card that its older brother was.
Original Radeon Mac Editions are hard to find. It took me several months to score one after the weaknesses of the RME 700 were revealed, and I paid a premium for it.
Suggestion: whatever card you get, try it with the built-in driver sets that come with Jag
before installing newer drivers from the ATI web site. I used the new drivers on the 9200's CD and they reduced my 2D performance (scrolling, Dock functions, etc.) by 25 percent according to XBench benchmarks. When I had to reinstall Jag, I tried the 9200 with the OSX bundled drivers and the 2D performance returned to their old levels and the card works fine.
Again--I can't say this enough--remember you are shopping for a PCI card, not AGP. The AGP cards are getting more common on the used market, and some sellers on eBay aren't even showing PCI or AGP in their product descriptions.
Here's the link to a response I posted in December that covers most of the ATI PCI cards:
