Just like the title says is there any real difference between a 2 and 2.2 ghz proc. in the MB in Leopard? I'm slapping 4 GB ram in the MB when I order it next week and I know RAM sometimes makes the better difference than a .2 ghz proc. increase. All I'll be doing with it is using it to take notes, write papers, do itunes, maybe even try some Garageband remixing of NIN tracks.
