When I first started exploring the issue with my "new" (about 6 months 
old now) machine (e6850 3GHz dual core intel w/ 4 GB RAM) the rule of 
thumb I learned was if you have <2GB of RAM i386 if more then AMD64.  
Sure you can use PAE on i386 but it is really a workaround.   Now there 
are about 10% of the ports out there that will not run on AMD64 with the 
most important "everyday" one being the nvidia driver for xorg (note 
though contrary to the man page nv does support the max resolution of 
your card/monitor [well almost I ca get 1400x1050 but not 1600x1050 on 
my 8400GS and 21" wide screen]).
