In my case, I used 64bit just so I would *never* have to worry about  
hitting a filesystem size limit. While I'm not sure if it still  
applies, there was a limit of 2TB for a filesystem for older kernels  
(or was it just for ext2?).

There should also be a performance increase as apps compiled for 64bit  
can access double the number of registers on the processor. With 32  
bit apps, even on a 64 bit processor you're limited to only 8 local  
registers.
