Personnaly speaking, i would not that easily accept a benchmark without
doing it myself first ...

Secopnd, why didn't they compare the dual-G5 to its real counterpart
(what you will get for the same price): Opteron or Itanium.

I'll bet they figures will be dramatically different. The dual-G5 is not
a working station but a server for desktop, so let's consider the server
solutions !
