A 32-bit system one process can adress approx 2 Gb. If you have processes that 
could require more than 2 Gb of memery, 64 bit is the only way.  Thus, 64-bit 
has advantages starting from 2 Gb of memory requirement/process rather than 4 
Gb. Advantaves is perhaps a bit subtle wording as I guess 64 bit makes 
something possible that is impossible with 32 bit.

I guess the applications as well as the OS has to be 64 bit for this to work.
