There ARE architecture differences between the two computers other than dual
core vs. separate processors:

1. The new dual core computers have faster memory

2. The new dual core computers use a newer PCI bus (PCI Express, which is
not physically or electronically compatible with PCI-X). There is no longer
an AGP slot. The PCI Express slots are either "4-lane, 8-lane or 16-lane".
Apparently they all have the same physical connector, but the speed with
which things happen will depend on which slot you put a card in and the
intrinsic capabilities of the card.

My guess is that the eagerness with which people look forward to the
performance of Apple's "Aperture" application will tell us a bit about what
this means in the real world shortly after Aperture becomes available.

I hope people will correct or amplify what I've said incorrectly or
incompletely.
