Hi, I want to get a new Mac in the near future. Im a bit undecided between getting a 27" iMac and a 17" i7 MBP. The MBP would be nice, because I can also carry it with me wich I obviously can't with the iMac. The system will be used for editing video footage from a Canon EOS 1D and my buddy's 7D. Question is: Will the 17" i7 MBP sufficient to handle this task? I'd combine it with at least one external display and a G-Raid connected via FW800 or eSata (ExpressCard). Thanks in advance.
