It also depends on how the system is set up. 

I think you'll find that people with fast recent PC's (or recently-
upgraded PC motherboards) are getting appreciably more speed out of 
their systems by using the new DDR system that lets you transfer data 
to main memory at 266MHz.  

AFAIK, the new macs (including the latest G4) are still stuck on 133, 
which puts them at a bit of a disadvantage, irresepective of how nice 
the processor is supposed to be.


Two-processor machines (PC or mac) don't seem to give anything like 
twice the processing power of an equivalent single-processor machine, 
and I can't help wondering how much of the gain is really due to the 
second processor, and how much is due to the second set of fast cache 
RAM that comes with it.
