So... I pose this question. When do you really need a 64bit CPU <other than the obvious potential need of a megasever needing the address space>?
By which you mean that you have so many Gigabytes of RAM that you are not even in the same state as the person writing the checks.
Most of the servers I know of run at less than 20% CPU usage 99% of the time, especially web servers. An application or LTSP server might be different, or somethign that had to to a lot of database whacking.
Generally, the problem with a server is that to get the IO performance you need you have to MASSIVELY overbuy on other hardware like the CPU. I would imagine that this is true of the 64bit architecture as well - it's not the CPU you're buying so much as the data bus.
