Formac sold the PCI Proformance III video card which was a contemporary with such cards as the ixMicro Ultimate Res and the ATI Rage.  Early 3D support.

So they were still around for a few years after the age of the Quadras.

I used to keep up with the upgrade market pretty well, and I don't remember such a Quadra upgrade, but that's certainly what it looks like.  It must have been kind of obscure.  Perhaps only sold in the European market?
