How much faster is the 3.33 v the 3.03 ghz? I.E if I'm ripping a movie using hand break will there be much difference ? Also will I be able to run more programs at the same time using the 3.33? I know I should wait for the upgrade, but my powerbook G4 is on it's last legs. I can only fit the 21.5 in my office. Thx.
