You do not say what amount of RAM and if you are running 32 or 64 bit but according to Adobe these are the figures
How much RAM can Photoshop access:
CS5, 32 bit Mac OS 2.1 GB
CS5, 64 bit Mac OS As much RAM as you can fit in your computer
Photoshop CS4 and CS5 require at least 2 GB of free hard-disk space (Mac OS). Additional free space is required for installation, and more hard disk space is recommended for virtual memory and scratch disk space.
By default, Photoshop uses 70% of available RAM! I do not know if this could have any bearing on the problem you are having but it may be worthwhile in returning to this level to see if the problem persists
