MBPPro 8 to 16Gb ram increase, worth it for aperture and D800

level of snappiness = x
level of snappiness after 1hr+ of editing = y
x-y=z where Z is the difference in snappiness

Add more memory and Z shrinks

Yes my x and y and Z may be different but the math translates across the board. Simple fact.

And the same math applies to load times with and SSD the only difference is the starting point based on chipset.

Disagree and some learning is in order on your part. max memory vs stock and OEM platter based vs SSD shows improvment on ANY COMPUTER

I didnt say the OP's Computer would be as fast as mine i said they'd see very significant improvements. Read better.
