Currently I have 2 monitors hooked up to my 1.8ghz powermac g5 with an AGP radeon 9600, and i've been wanting to add a 3rd one. Would any pci(i know not a pci-e) video card work for this purpose, or do only certain ones work with a mac? I'm not doing anything too crazy with it so it doesn't have be a high tier card, at most just email and web browsing.
