Now how would that work? The Voodoo 2 was a 3D-only chip. It didn't have a 2D engine, and used the same pass-through cable setup as the Voodoo 1. Did you route the onboard video to it, then the internal display to it as well? Or did it only draw to an external display? (I seem to recall one mez video card that would only run an external display, not the internal...)
(Ah, a quick search reveals that it has an internal-cabling-only passthrough.)
As for the color looking better, that would depend largely on the game. The Voodoo 2 chip can only do 16-bit color; while the Rage Pro can do 24-bit, so the Rage Pro should in theory be able to LOOK better, even if the performance is worse. (On the PC side, I bought a Matrox m3D back in the mid-to-late '90s, which was the first 3D accelerator that could do 24-bit. Unfortunately, it had lousy game support. But in those games it did support, it looked WAY better than a Voodoo. It also passed all the video data through PCI to your primary video card as an overlay, so no external dongle.)
