I found Win2K Pro the most stable so far. Those stories of XP not crashing? I've had XP for a few days and I would have to take my socks off to count the times it crashed on me so far. But I do agree, find an OS that works for you and your graphics and stick with it or if size of hard drive permits, install more than one OS on your hard drive. Dual or even Triple booting for all your needs.
