when do you really need a 64bit cpu?
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>? Most of the folks I know that have an Opteron or Athlon64 do not have any 64bit specific software, except maybe the Linux kernel compile.
The Duron and Athlon32/Barton both seem to be replaced by the single Sempron32.

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.

And before you say you'll never need that: HDTV 1080i is 1,080 scan lines x 1,920 pixels/line = 2,073,600 pixels x 24-bits/pixel in YUV format / 8 bits/byte = 6,220,800 bytes/frame x ~25 frames/sec = 155,520,000 bytes/sec x 60 sec/min x 60 min/hour =
559,872,000,000 bytes for 1 hour HDTV quality home movie of your daughters birthday party recorded on your brand-spankin'-new HD home camcorder stored uncompressed for editing. That's 560 gigabytes.
Other than that, you don't.

Ah ha! I completely forgot about 32-bit Unix time.
