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.

Using x64.

Only x64 programmes will run in 64 bit mode. All other programmes will run
in 32bit. There are not many 64 bit programmes available.

Even 32bit programmes will benefit by accessing more ram and not be
restrained by the 3.3Gb limit of 32bit OS.


Correct.
IMHO that is the only advantage af W7 64-bits.
