Anyone know how much faster a new Mac Mini would be compared to an old Mac Pro? I have an original 2006 Mac Pro with the 2.66 dual core xeon and 3 gigs of RAM. I do graphic design work, multitrack music recording and occasional forays into HD video. It's held up fairly well over the years, but it's starting to get a little bit ponderous and I'm thinking about an upgrade. I have three big internal drives (3 terabytes), and various other external drives connected to it. I could just pop for a new base Mac Pro (and I'm curious if my old internal drives will work in there). But it also occurred to me to wonder if just buying one of those little Mac Minis would give me a fairly substantial boost in horsepower, assuming I could network the old Mac Pro to it to have access to all its hard drives using its gigabit Ethernet port. The applications I run are InDesign, Photoshop, Final Cut Express, Logic Studio. Any thoughts?
