David,
Since I’ll be purchasing an iMac i7 with 8GB memory soon for video editing, do I still need to copy media to a FW800 external drive even with the processing power of the iMac i7? I assumed that the iMac’s system drive would be more than capable to handle whatever editing in FCP 7 and/or other FCS 3 apps that I would have open, thereby not requiring the use of an external FW800 hard drive. Am I wrong in my assumption? By the way, I’m a new user of Mac hardware, so please bear with me.
