Kamm!

	I am (or was) a CPU expert.  And you are right - the path to the memory
is still a bottleneck.  But so is the path to the video card, the Hard 
drives,
the Firewire ports - etc.

	The dual G5 architecture is Extremely Elegant!  No other way to 
describe
it!  It is as efficient as current (or one year old) technology can do.
In the real world - this type of architecture should average out to 
about
a 30% improvement over a single processor - because of all the
other bottlenecks.  All things considered - it is an amazing improvement
over the past systems - and will only get better!

Just my 2 cents worth!
