In general, that's true -- excepting 64-bit arithmatic-heacy apps, for 
example, but x86_64 has other advantages of i386, including doubling the 
number of registers in the processor.

My daily work (heavy compiles, photo manipulation) is noticably faster 
when running with 64-bit binaries.  

(that said, my experience with sparc64 showed a slowdown in 64-bit 
 userspace.  except, again, when heavy number-crunching was employed.
