How much RAM do you have?

[Libby Pritchett]

I'm having such issues lately with warnings that I'm running out of RAM when I run Photoshop CS6 64-Bit in Windows 7 64-Bit. I currently have 16GB of RAM, and I always thought that was plenty, but I'm wondering if my thinking is old-school and maybe I *do* need to install more.

I currently have 85% of my system RAM allotted to PS use, but that still puts my efficiency rating at like 80% when I'm running PS (which means that it moves to my scratch disk to run). I just went through and cleared out all my presets, so currently, it's running better. But I constantly add and remove presets while I work, so it's sorta important that PS can run with those installed. LOL

Anyway, how much RAM do you have? Any other ideas on things I should be checking?
