In theory, the OS can do a much better job of managing the left-over RAM than the RAM disk software. And in our tests, RAM disks don't help, they slow things down." And, while I can't speak with great knowledge regarding Macs (since they may manage / use memory differently than Win boxes) 13GB (16GB minus 2GB for PS minus 1GB for OS) may be somewhat marginal for swap space and a scratch disk, especially if you're working with large files. I'd also be concerned about what might happen if both the swap file and the scratch disk were writing to the RAM disk at the same time. Shel "You meet the nicest people with a Pentax"
