Hello, I am in the market for MBP, 13" (2012 models): Option 1, is to get i5 base model with 8GB RAM. Option 2, is to pickup a refurbished i7 model which has 8 GB RAM and 750 GB storage. The price difference is about $50 more for refurbished one. I am just a normal user, new to MAC, and planning to use MBP as some light code developing and etc. Not going to run COD kind of games Which one should I go for? Thanks in advance!
