Hello all!! I have a 2011 Macbook Pro 13 Intel Core i5 Sandy Bridge 2.4 GHZ with 4 GB Ram an upgraded HD Momentus XT Hybrid Drive Now.. with this config I'm having a hard time editing photos on Aperture, Lightroom and Photoshop specially when messing with RAW files and multiple layers. Adding RAm up to 16GB will help or should I sell it and get a new Macbook Pro.. probably the new one coming with the HD5000 and 8GB Ram? How much should I ask for if selling is good idea? Help appreciated!!
