32bit vs 64bit (was: Just like Christmas)

Interesting. We've got a 4-way K570 w/3GB mem that we'll be moving from HPUX 10.20 to HPUX 11.0 this weekend (8 hours of watching tape spin), which means I can FINALLY get us to 8i! YAY!

So, why or why not should one go to 64bit? Here's my perception:

        Pros
        ---------------
        Should be faster (moving 2x as many bits around)

        Cons
        ---------------
        Requires major downtime to go from 32 to 64.
        Patches don't seem to come as quickly as 32bit versions on HP.

        Unknowns (for me)
        -----------------
        How much faster, if at all, and in what areas (mem, I/O, disk)?
        Possible client problems?  Our clients are all 8.0.5 for now.
        Any difference/disadvantage if 3rd party OCI programs are
                not recompiled?

TIA,
