Probably not. You will be gaining x2 storage and going to a Haswell. I cannot claim expert to my opinion. I currently have the 2012 2.7/16GB/768GB and cannot pull the trigger. Gazelle offered me $1,281 for mine but that won't offset enough to pay for going to a 2.8/16GB/1TB.
Maybe we both should wait until next year.![]()
Don't EVER sell your Mac to Gazelle, unless you want to be paid a lowball price. Compare the prices that your machine is selling for on eBay to what gazelle offers, and you'll see what I mean.
