When choosing my matrox g400 drivers for win2k, the website gives me three choices. the "latest drivers", which they say are beta, and are not supported by matrox graphics techical support; the "WHQL drivers", which are certified driver releases; and "Unified drivers", which are one driver that supports multiple matrox video cards. Can anyone enlighten me on what the difference is between these choices and which ones I should be using for playing games and such? Thank you for your time
