bah.  buying chips based on their address register width makes 
about as much sense as buying based on clock.  yes, some people have 
good reason to be excited about 64b hitting the mass market.  but 
that number is quite small - how many machines do you have with 
>4 GB per cpu?

remember, Intel has always said that 64b wasn't terribly important
for anything except the "enterprise" (mauve has more ram) market
(mainframe recidivists).  I think they're right, but should have also
adopted AMD's cpu-integrated memory controller.

maybe instead of a bazillion bytes of cache on the next it2, 
Intel will just drop in a P4 or two ;)
