Wayne: Thanks for the quick reply. Just checked out the DP upgrades on OWC's site. For $400 minimum, I'll probably pass, but if prices ar dropping, it might become a viable option. Does OS X take full advantage of these DP upgrades in the older machines? IE, is it fully symmetrical, or is there still a "primary" and "secondary" CPU?
