Off the top of my head, giving photoshop all the RAM
may not be a great idea.
Photoshop has its own virtual memory management
based on tiles. If the OS needs the RAM for anything else,
it will likely be kicking out photoshop's caches from
RAM, which will result in photoshop's virtual memory
management essentially working counter-productivly.
Try not giving it too much more over half of RAM,
the OS still needs ram for caches and more. Also
start Photoshop after any other apps you may be running
at the same time.
there is also apparently a plug-in in CS2
that will make the tiles in the cache larger;
google for "Bigger Tiles plug-in" for instructions
