I never had problems, like strange mouse movements, mouse jumpung or things like that. But what i noticed after installing OS-X onto 2 AMD machines, one Intel C2D desktop and Intel C2D laptop machine is that somehow on my amd machine mouse movements are somehow very unnatural comparing to windows or linux. Its very annoying. On intel machines its just great but only on AMD machine very unnatural and really not comfort using mouse as in windows. I tested with 3 different mice, the same. I am used to this almost, after 5-6 months, but what i wanted to say is this kind of movement i really didnt notice on my other Intel machine.
