Actually, no. Remember, 64-bit is only new to the consumer stuff. I've been running 64-bit UNIX applications for over 8 years. 64-bit UNIX has been around even longer than that. It's not a matter of "horsepower" (by today's standards, a 167MHz UltraSPARC I is kinda slow...), but of the usefulness of a 64-bit address space, not only for real memory, but for virtual. As well as higher precision, etc. (Assuming the CPU is true 64-bit and not limited by a smaller external address bus.)
Hmmm... There's actually a good entry on it in Wikipedia:

That might help you some more.
