I've been around the 64-bit world for a long time (digital Unix on 
Alpha).  Working with the x86 and x86_64 families, I've found that many 
applications certainly perform better at 64-bit applications, but I have 
also seen many cases where  32-bit application may perform better than 
the same application in 64-bits.. In general, a 64-bit OS will support 
both 32-bit and 64-bit apps, and some 32-bit apps will perform better 
with a 64-bit OS on x86_64. (Itanium is a different story and I won't go 
there).
