My 2006 Core Duo iMac is currently on its last legs, and I'm looking to get a 27" replacement this year. I saw a 2011 refurb (3.1GHz i5, 1TB HDD, 4GB RAM, 1GB GPU) for about $600-700 cheaper than the configured 2012 (3.2GHz i5, 1TB Fusion, 8GB model, 1GB GPU) I'm looking at. I will mostly be doing work in Adobe CS, some Java development (learning at home) and would like to do some gaming (native Diablo 3, Half-Life 2), and possibly Bootcamp. I would be buying AppleCare for whichever I pick. A few questions I have are below: 1. Is it reasonable to expect a spec bump / price drop (however insignificant), by fall 2013? 2. Does the '11 model have a significant amount of glare compared to the '12? The screen will be facing a north-facing window. 3. Once I upgrade the RAM to 16GB on the '11, will there honestly be that much of a difference in performance? Appreciate any help you can give me.
