I don't know much about the first PC that I owned and played games on, it was a custom PC that my dad built and he doesn't recall anything about it. For certain, though, I know what graphics card the PC had. It had a Matrox Mystique, a card from 1997 with which I played its exclusive version of MechWarrior 2, among other games.

I still have the driver installation disc, and dug up the beautiful video within demonstrating all the features of the card.
