There is no relationship between an application being 64bit and its use 
of multi-core/multiprocessor architectures.
One thing to note, however, is that pre-Windows 7 versions of Windows 
will lead to reduction in performance running hyperthreading-enabled 
cpus (such as Gulftown, Lynnfield, Bloomfield an Clarksdale), so if 
you're running Vista or XP, other processors (e.g. Arrandale) may 
perform faster with non-multicore apps although "by spec" they should be 
slower.

The newer architectures (Nehalem and followups) also enhance on running 
non-multicore apps via their frequency binning - also worth noticing.
