Hi guys - I have to ask a dumb question because I am not a computer wiz-kid. Presently i am playing Diablo 3 on a powerful micro soft laptop which gets very,very hot during game play and I have an external fan keeping the temp. down. So I had the idea of moving to a Mac Pro which has a bigger screen. My question is: will I loose all I have achieved from playing on the micro soft pc, when, and if I buy a Mac?
