Thanks for the clarification. Yes, the actual architecture (how many cores, how many chips) is really only of interest to the motherboard designers, and to people who think they are up against system-level performance issues (which I doubt anybody running Logic on an eight core MacPro is going to be.) There are ways of putting eight 3GHz cores together that will be somewhat faster than other ways, and folks who like to focus on having the absolute god-awful fastest machines will wring their hands over such things and the rest of us will marvel at how a 32 track mix at 96K with a bunch of plugs uses all of 5% of the capacity of the machine. ;-) But from an application standpoint this is all completely hidden by the kernel. --Dave
