Profound circumstances allowed me to track down a 2012 13" cMBP with the 2.5 chip for what I considered dirt cheap. Hours after getting it, I then see someone on Craigslist with an October 2011 15" base system that they want to trade for a 13". I've browed various sites for synthetic and virtual benchmarks compared different chips, but am looking for any feedback from others on what you think on the 3210M vs a 2675QM. My personal opinion is that either would be overkill. I am trying to stay away from my Steam collection of games, but even then, the HD4000 is sufficient at 1280x800. If the 15" were 1680x1050, I would jump all over it. Since it is 1440x900 though, I am more hesitant. Anyone want to comment on what would be a reasonable amount for me to add to the 13" on the cash side of things to make it fair, as well as if it is a considerable performance jump for me to have it?
