    Do I have to run the OS (10.6.3) in 64 bit in order to get full 64 bit benefits of PS CS5?

      I keep reading about the benefits of running PS in 64 bit, especially for very large files (which is most of my work). I was under the impression that applications can only use more than ~ 3GB of memory if the operating system is running in 64 bit mode. However I still run mine (Mac OS 10.6.3) in 32 bit (the default mode) and still, in the "Performance" preference panel of PS I can allocate my entire amount of RAM (14GB) for Memory Usage.

      Am I getting the full benefits of 64 bit or do I have to run my OS in 64 bit?

      Thanks for any bit of advice...
