Hi all I really could use a bit of help deciding on which Macbook Pro 15 inch to buy (i'm looking at second-hand). I've been offered a 2014 Macbook with 2.3 ghz, 512 GB and NVidia Gforce GT 750M 2BG graphics. Also have a few scratches and dents. http://www.everymac.com/ultimate-mac-lookup/?search_keywords=ME294 I have also been offered a newer (2015) version (without the new touchpad), 2.2 ghz and 256 GB. I really don't need the extra GB but do occasionally do some gaming (CS and Dota). Both laptops are priced exactly the same. Which would you pick and what should I be aware of? Thanks in advance for your help! Really appreciate it.
