A few years ago, when the 64-bit Opterons were still relatively new, I
read this article on the HyperTransport (HT) architecture in SysAdmin
magazine.  At the time, according to the article, out of all the
different companies selling Opteron-based systems, the HP Proliant
DL-585 was one of the few that fully implemented the HT architecture.

So yeah, there' s a lot more to computer performance than the type of
processor and socket on the motherboard.
