Okay guys, so I've been waiting for a while now and I'm at my breaking point. I'm falling behind on projects and am starting to think I can get a better deal on a 2011 refurb than the potential 2012 imac that may not be. I can get the 27'' 3.4ghz i7 with 1TB internal and the Radeon 6970M for $1890 refurbished. Figured I'd upgrade the ram to 16gb myself. So it makes me think, what am I really going to be missing from a 2012?? USB 3 obviously, more possible solid state options and a possible 10% increase in CPU and GPU? Plus id be paying quite a bit more to get these type of specs in a brand new machine. So is it really worth it?? What do you guys think?
