Here's a real-life example: I have a Dell computer that came with a Diamond FireGL 1000 Pro 2D/3D card (based on a Permedia chip). I added 2 Creative Labs Voodoo2 cards in SLI mode. The output of the Permedia card goes into the input of the 1st Voodoo2 card and the output of that card goes to my monitor. When I run Glide applications, my Voodoo2 boards are used automatically, no questions asked. However, when I run a DirectX application like BattleZone, DirectX first pops up a dialog box asking me which 3D card I want to use. I can choose either the Permedia solution (which looks terrible!) or the Voodoo2 solution. I'll let you guess which one I usually choose... The only issue for combining a Banshee based card with a Voodoo2 based card is whether or not the Glide drivers will give you a similar dialog box for choosing between the cards when running a Glide-based program.

From my understanding and what I have observed is that: Those applications using the API (Application Programming Interface) for the 3Dfx hardware acceleration: Direct3D, Glide, and OpenGL are going to cause the Voodoo2 card to take over - i.e. ignore the ministrations from the 2D/3D card if the Voodoo card is the "Primary 3D". The 2D/3D processing that are not "taken over" will be passed through with essentially no intermediate processing by the 3DFX card. In the Pure3D tab under Display there is a way to set the Pure3D as the "Primary 3D". I don't know about banshee, but I suspect the issues are similar.
