Yeah. I didn't realize this was an option either, until I visited the FAQ page on there site for the Voodo3 2k.
I'm just wondering if the decreased processing speed of the voodoo2 will hinder the processing speed of the voodoo3. Maybe it doesn't matter, but since the voodoo3 video signal will have to "pass through" the voodoo2 card, maybe the signal will slow down.
I could try this configuration, but I haven't ever done FSP readings on my computer before, and don't really know how.
