I'd say, let your applications decide for you. Application compatibility
(especially 3rd party) will be better on i386. But if you don't have any such
issues x86_64 is the way to go.
The 2nd thing to consider is memory addressing, this will be better on x86_64
(especially on your 4 GiB box). i386 will split your 2 or 4 GiB into low mem
and high mem and that will be harder for applications to use than the flat
model provided by x86_64.
And in the end, if at all, consider possible performance differences...
