Not only that, but it was the beginning of accelerated 3D graphics in consumer PCs. There was never another leap as big as the one provided by getting a 3DFX Voodoo. I remember it fondly.
I use to dump video from a TV Tuner card into the linear frame buffer of the 3DFX Voodoo card. Instead of using the pass through cable I used two monitors. It was my first multi-monitor setup.
