I'm thinking of upgrading my Matrox mystique card to a Matrox Marvel to be able to do video editing. I also have a voodoo 1. Would I still need the voodoo 1 in my system, or does the marvel offer superior performance to it for games. I'm just a casual gamer so top notch performance isn't really an issue. Also what is the OpenGL ICD driver for the matrox cards, why is it needed if games support Direct 3D?

Yours answers are greatly appreciated.
