[CUBE] Powerlogix 1.2GHz vs. dual 800

[Michael McPherson]

While the specific comparison you want isn't available here, the 
following page contains
several benchmarks of several G4 configurations (with single and dual 
processors).
It might give you a good feel for some of the performance you might 
expect.  There are several different types of benchmarks. Things such 
as hard drive upgrades (a 7200 rpm hard drive seems to make a big 
difference here in performance over the cube's stock 5400 rpm drive) 
aren't taken into account here apparently, but it still is probably 
worth a look
