Read this for a comparison in performance for 32 bit, and 64 bit linux: http://bingouv.blogspot.com/2008/08/desktop-linux-performance-comparison32.html .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).To summarize, you will notice the difference between 32 bit and 64 bit for CPU intensive tasks. But it won't change the world. This comparison is based on Fedora-9.
