Hey guys, so I'm about to buy an 8 core mac pro with one 640 gig hard drive. My question is basically about whether or not I should buy some external drives to use as studio drives, or if I should buy some extra internal hard drives for the computer instead? I'm trying to avoid the dreaded CPU overload message, and I have had to deal with it on my MBP for some time now, so I want to make sure I can do everything to optimize my new MP for Logic. Thanks guys!
