Sorry if this topic has been covered before but I am going to be purchasing one of the new 21.5'' imacs, and i want to be sure I make the right choice. The main thing i will be using the mac for is Logic studio, my budget is not massive but i could raise the extra £250 for the high end version if recommended. But will I really need the extra 500GB hard drive? or the slightly better processor? If Logic will run just as good on the base model then i would rather get that to save a bit of money, but I don't want to have the base model a few months, only to realise that I should have gone wth the higher end version. Thank you in advance for any help.
