A better rule of thumb is never run a 64-bit processor for tasks that don't require the address space it affords.
If it's a better rule of thumb than only by a rather slim margin. Pros for x86-64 I've not yet seen are for instance that the compiler is able to do things better on x86-64 because there's quite a few additional registers available. Or that the split of address space between Kernel and user space is differently on x86-64 in that user space gets quite a bit more of it. Plus it has served to discover lots of sloppy programming that was only revealed because int and long where not of the same length. But that's more of a benefit for programmers than for users :) And what about memory mapping files? PAE won't help you one bit there as you're limited to the range of a 32 bit pointer.
