There are many reasons why I would choose 98 over 2000 for gaming. One problem is the video drivers, even though theyre getting better, theyre not there yet. Nvidia 2000 drivers dont even have digital vibrance control! Also, as stated some games just refuse to run, and most run a tad slower. Also, I've noticed some other stranger problems with win2k, like a slight delay in mouse movement in counterstrike, and 3d sound doesnt always work properly on my sb live.
