Worth upgrading from late 2011 to mid 2014?

Hey y'all! Been using a late 2011 on sequoia for a while because of repairability/upgradeability, firewire, full size lan, and ODD (which i didn't like actually use, but still cool) and i do love it, but yeah it is kinda slow sometimes, the screen resolution just isn't really there and no metal support is a pain in the ass.

If everything goes well, i'm going to study informatical engineering next year, so i need something proper and battery life is also pretty important.

So i found a listing of a mid 2014 i5 for 150$ and i'm really thinking about it, is it worth it, what should i know about those models? Thanks!
