Im looking at buying the new 3.2gig MacPro but i was under the impression that the new .45nm processors were the Penryn processors for the Mac Pro. ON the specs of the machine it says they use the 45nm but they are the Xeon Harpertown processors, however on the front page of this site, it says something like "it appears correct apple buying up the new 45nm penryns"/. so im confused. i rang apple and they are so friggin dumb their tech support and sales staff said -"sorry we dont have that information" ????!?! so im confused..help please!!
