Hi I know this topic has been beat to death but I'm still stuck in making a decision about this. I have the option to get either a refurbished 2011 i5 27 inch (and upgrade the RAM myself to 32gb) or to get a new 2012 21.5 inch with the 640M processor/ i5 2.7ghz, 16gb of RAM, and no fusion drive. My primary use (that actually matters) is aperture and photoshop editing large raw files. So what do you guys recommend? Thanks in advance!
