Hello everybody! I have currently owned the MBP 13" Early 2011 with i7 2.7GHz, 8GB RAM and 7200rpm HDD included. I wish to upgrade the computer and seems like I have 2 options: 1) upgrade RAM to 16GB + add 500GB SSD and install current HDD in OptiBay 2) buy MBA 13 Mid 2012 with i7 2.0GHz, 8GB RAM and 512GB SSD + external HDD on USB 3.0 I know all the advantages and disadvantages between them. Better resolution, mobility, more ports etc etc. My main question is about performance. Which configuration should be faster? I check the results at everymac.com however there were for the standard versions (MBP 13 with 4GB RAM and HDD 5400RPM vs MBA with 4GB RAM and SSD 128GB). 4 times more RAM makes difference, right? I use the laptop mainly for editing pictures (Lightroom mostly, I don't use 100 layers in Photoshop) and editing movies in Final Cut Pro X / Premiere with encoding it in Compressor 4. So, which laptop would be better for this job? Ah, and I use external LCD (1900x1200) for this, so the native resolution is not an option here (even if i wish to have 1440...). Can you help me?
