I have a Late 2011 13" MBP with the 2.4 I5 processor. Over the last year or so I have noticed my computer running extremely slow when opening various apps (iPhoto, Excel, etc.). I have 200 gb free on my hard rive and the memory pressure shown in activity monitor remains low even when computer is slow. To increase speed, I'm looking to upgrade to a SSD as well as add more RAM. I'm currently at 4gb. From what I've read, the SSD will be a huge upgrade. Concerning RAM, Is it worth spending the extra coin for the 16 gb ($170) over 8gb ($80). Not sure at what point my cpu will be the bottleneck causing the other upgrades to net little improvement. Thanks for any input.
