ISTR that the early R10K O2s (150MHz and 175MHz) were stuck with a poor
design that hurt memory bandwidth (or something) and performance
(relative to other, similar R10K CPUs in other systems). From what I've
heard, I'd say go for it. (But there are others in this newsgroup who
are more familiar with the O2 architecture than I am, who can elaborate
on what I think I remember reading.)
