I had a Canopus Pure3dII and a Matrox Millenium 2, and had
to give up on them about 1.5 years ago.
Matrox quit updating the drivers for the Millenium 2
after directx6. The continuing series dx6, dx7, and now dx8a
combined with game patches would cause my computer to
crash. The most frustating thing was that the game
would crash during in a 2d grafix setup screen, not during the
game.
You will be able to play CounterStrike, which is based on
a 2.5 year old game (HalfLife)
