If you have 2gb or less memory and you don't use memory intensive calculations
than go with i386. Programs can use around 30% (IIRC) more memory with amd64
than with i386. You also won't see any speed benefits unless your programs do a
lot of memory intensive calculations where you will benefit from the extra
registers (mostly if you are developing mathematical software)
If you intend to use more than 2gb memory install amd64

If you compile yourself you can also optimize for core2 but I don't know what
you will gain (that is only for the kernel the packages are amd64)

ia64 is itanium systems (corporate servers mostly)
