I can say that xp isnt very good. I am having unusual issues with xp that should just never happen. I cant play quicktime movies, even though i have qt installed. No error message pops up. Task manager opens for 3 seconds and dissapears. Thats no good if I lock up maya when doing something with a hi polygon count. I was using 2k before..and I am going back to 2k. Maybe its my hardware..but 2k never gave me those #$@%*!! problems
