One other thing that will control what's happening in photoshop is your Hard drive, and how much space photoshop has in it's cache partition. You gotta remember, EVERYTHING you do goes to history, and undo. purging often, helps to keep a reasonable speed in what you're doing. Having a dedicated partition works very well.... for example, I assigned E for one of the caches, and try not to store anything there. Hope this helps, Lou.
