Hi! I just recently purchased the Retina 5K Display 3.8GHz Processor 2TB Storage with i7 upgrade. I am a video editor and photographer using Premer Pro, Lightroom and Photoshop as well as some other programs. I would like to upgrade to 32GB of RAM! Any RAM recommendations? I am also looking for a UPS (battery backup) solution and a second monitor that is affordable. Also, if you have any recommendations of accessories please share! I am upgrading from a Mid 2010 MBP! Thanks!
