If you use 32-bit applications which benefit from using as much
memory as available, you will see a significant performance boost
when running them under Win7x64.
Each 32-bit application is allocated a full 4GB of RAM in x64,
instead of 3.something which is available under XP 32-bit.
If you had (say) 16GB of RAM, x64 would allow Photoshop to use
4GB, plus app2 using it's *own* 4GB plus app3 using it's *own*
4GB, all running simultaneously.
I can state from my own experience of using 32-bit image processing
(astronomy) software that using x64 is a huge advantage in my work.

Hi Rob,
I see your point. But I don't use a specific application that would benefit
of more memory.
One exception may be VMWare. Sometimes I use a situation where I have
multiple virtual machines running on a virtual network. In only that case I
would benefit from more memory. But this does not happen often.
On the other hand, I wont be able to use some applications as they won't run
on W 7 64-bit.
