I just pulled the trigger to up the memory on a mid-2012 MBP 13" from 4 GB to 8. $54 shipped. Not sure it will help with a i5 processor but I still love the hardware. I normally use Chrome for all the developer add ons and what was once a fast tool. I just brought up my activity monitor and there are 5 different GC processes running when it's up, I have ABPro installed and running as well. I just don't have the bandwidth to keep up with all this...starting to not care about internet anymore. Edit...haha as I am posting here.
