Hi, 

I have experimentally found out, that 64 bit Linux distro uses like 40 -- 80 % 
more of RAM than 32 bit. Now it seemed to be both aplication and distro 
dependant, with Arch being on the better side. Though I've got to say again, it 
was not a benchmark, just my personal experiment.

As for me, if I had a machine with plenty RAM (that is from my perspective 
~GB), than I would choose 64 bit. If I had like 1 -- 2 GB, than I would 
definitely go 32 bit.

Hope I did understand your question right.
