Hello everyone, this my first thread in the macrumours forums, although i've been hanging around the site for over a year now. i'm looking to buy the 13 inch, 256gb SSD macbook air in about a months time, and i've already decided on 4GB of ram. i was wondering if the jump from 1.86ghz to 2.13 ghz might be worth it aswell? my main uses are safari browsing, email, skype, imovie, iweb, garageband, light logic work, and a few games (cod 4) and torrent programs. would the 0.27ghz jump be noticeable in any of these? and would it make much of a difference when exporting projects from imovie? thanks for the help.
