Hi, I'm thinking of picking up a 13" from the refurb. store. http://store.apple.com/ca/product/FC965LL/A My hesitation is whether or not it's worthy of the extra $300 or so to upgrade to the newer model with better GPU and quieter/cooler Ivy CPU. I've seen reviews of this machine running Premiere and Photoshop with aplomb when they first came out so that doesn't worry me. So difference are: - slightly faster/cooler CPU - faster USB3.0 - Faster GPU of 30%? Apart from those changes, everything else is pretty much the same, right?
