I got to digging around on this subject, and discovered to my surprise that in a great and mighty pile of Mac junk in the basement, I actually have the box that the Voodoo 5 5500 came in. I hadn't remembered that. No manual, alas. What the box says is that BOTH processors on this card work in tandem, with 64 MB vram.

An XLR8 review, however, speaks of how an early driver disabled one of the processors - a problem fixed later on. I haven't confirmed that myself.

I discovered on the box too that the resolutions supported are as follows:

1152x864; 1280x1024; 1600x1024; 1600x1200;1920x1080; 1920x1200; 1920x1440; 2048x1156.

Well, Apple's current 23" LCD is optimized for 1920x1200, as are many others that run at half the price....
