What is best video card for Dual G4 867

[howardnow]

I can't seem to find any recent information about a video card upgrade for my Dual G4 mirror door 867. I have 2gb ram and a fantastic 21" Gateway HD LCD monitor.

What is the best upgrade video card for my computer (hopefully at a
reasonable price).

I would like to run Motion. Will the video card help Final Cut Pro and IDVD?

Thanks!!!
