I currently have a new mid-2010 MacBook Pro 2.4Ghz. I really wish i had gotten the i7 now, but to late! Is the new i7 really "quad core"? I have been hearing that both the i5 and i7 are dual core processors. I know they are both recognized as quad core by the computer (Excel recognizes mine as having 4 processors when doing calculations). Are they both recognized as quad b/c of the turbo boost feature? So my real question is what the dif in the i5 & i7 processors? is the i7 a true quad core? Is it worth me selling my current i5 2.4 and getting an i7?
