'full power' might be stretching it.  The EM64T chips can address more
memory without PAE hackery, and have a few (a few, not a lot) more physical
registers, but that's about it.  It's not like they have better
buses/caches/whatever.  Unlike Opterons, which have shedloads more registers
and much better memory bandwidth - *especially* useful for multi-CPU boxes
like, er, Dell servers (hint hint).
