not true. but it's true if you need over 3GB of VM for single process.

this way it doesn't make sense of buying 64-bit hardware.

i use FreeBSD/amd64 (6.0) and it works excellent.

other tasks get from this adventage too, maybe not that much. lowest end 
AMD64 machines gets same memory bandwidth that high end P4 machines for 
1/10 price :) (and still having lower latency).
