I see the benchmarks that OWC does that show large performance gains on things like creating 50 GB images in Photoshop. Can anyone tell me how much more RAM improves (or doesn't) performance on more common tasks such as web browsing, Office, basic Photoshop on typical image files (rather than 50 GB ones). Would I see performance improvements across the board on just mundane tasks if I was to upgrade from 8 GB to 16 GB or more? At the moment, Activity Monitor shows my memory use at about 5 GB. I wonder whether or not if I had more RAM headroom OS X would take advantage of it by shifting more items into memory (e.g., if I had 16 GB to capitalize upon OS X would be utilizing 9 GB or something rather than the current 5).
