The 2D/3D Voodoo Rush performed so poorly that there was an offer to return the 3D daughterboard in order to get a proper standalone Voodoo card. You could still use what remained of the card for 2D. I did this and they sent me a retail Diamond Monster 3D.
I thought I was buying something better than a Voodoo and got it at release before there were any reviews. Lesson learned.
