Will I see a difference from 8GB to 24GB RAM?

The machine is a base model 27" with a Fusion Drive. I need some convincing on shelling out some more money after dropping 2500 just recently.

To determine if you can benefit from more RAM, launch Activity Monitor and click the System Memory tab at the bottom to check your page outs. Page outs are cumulative since your last restart, so the best way to check is to restart your computer and track page outs under your normal workload (the apps, browser pages and documents you normally would have open). If your page outs are significant (say 1GB or more) under normal use, you may benefit from more RAM. If your page outs are zero or very low during normal use, you probably won't see any performance improvement from adding RAM.

What are you going to do with it? Page outs are a good indicator, but they can be misleading. If you never quit programs, have tons running or have buggy software that leaks memory, it may not be the whole story. Also, how often do you restart your computer, because that resets the count. I know some people are anal about uptime, so it's worth knowing.

They're not misleading if you follow the instructions in my post.
