That is what I am thinking. I have not opened up the computer and  
inspected the PCI Express slots to see if they have different  
configurations.

No I have both computers running the same OS 10.4.8. The slowdown is  
most likely a Rosetta issue. A neat menu item would be a little  
indicator for when Rosetta was executing code. It certainly would be  
interesting but I suppose you would need to have a light for each of  
the 4 processors.
