[CUBE] Powerlogix 1.2GHz vs. dual 800

[Bill Fox]

My general experience with benchmarking many processors is that for 
*Dual Aware* applications the second processor adds about 30-40% to the 
effective speed, i.e. a dual 800 would run like a single 1.1 GHz or so 
but just on those few applications. On every other application, a dual 
800 will run like a single 800. OS X's Finder is dual aware so a dual 
800 will be faster than a single 800. The single 1.2 GHz should be 
faster than the dual 800 for every operation.

Of course, this is just an educated guess and if you really want to 
know, you'll have to wait until they ship and somebody benchmarks them. 
I suspect the distributor OWC (www.macsales.com) will be the first or 
among the first to do so.
