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?
