Perhaps when you attempt to convert some PDF (heaven forbid!) into an epub being really adventurous ... Not really recommended 
Besides Kovid told me that he did not noticed any speed improvements when I asked him more or less this same question about a year ago. So I decided to just stick with the 32 bits version.

It's not really about the size, and anyway IIRC pictures do not need to be converted, just pointed to in the final result.
Some wild ebooks (PDF is particularly exciting) require a lot of processing just for calibre to figure out how to "translate" it. The problem comes from the particular markup used.
True enough that 64-bit is not a magical speed improver... if nothing you do uses more RAM than the max 32-bit cap, then 64-bit won't help.
It won't hurt either, but most things won't really be helped.
If my computer was a 64-bit system I would use the 64-bit version Just In Case
(Of course, on linux it will automatically choose the 64-bit version for you.)
