Performance is equivalent, except in a few corner cases. Keep in mind that
there are some cases where amd64 is actually slower, so it's really a wash,
unless you know you're specific application will benefit from 64 bit.

Personally, I would stick with i386, unless you like to experiment. Last
time I tried to run amd64 on a desktop, I had lots of trouble with misc
problems here and there. Same machine running i386 is rock stable with
no problems. My gut tells me that a lot of desktop apps and libraries
aren't really mature from a 64-bit standpoint yet.
