I have an early 2011 13" MBP i5 2.3GHz and I upgraded to 8GB of memory a few months ago. I might be selling the MBP next week. I ordered a Samsung 830 SSD 256GB that will be delivered to my house tomorrow. My uses are for the MBP are basic things such as internet, work, email, etc. I do not play computer games at all. I would like to if its worth it for me to upgrade to the 2012 13" MBP i7 or 2012 15" Base MBP?
