Orchid Righteous 3D - 3Dfx - 4MB paired with a Matrox Mystique 220 - 4MB.
The first game I played with native glide support was TOCA/TOCA 2, I was blown away.
Kids of today have no idea, I doubt most of them know what hardware accelerated graphics are. Remember the pain of running the latest 3D game using directx? (before hardware acceleration).
To this day, experiencing hardware acceleration for the first time is the biggest WOW moment I have experienced while gaming.
