I would like to get some opinions. I am going to buy a new iMac and wonder if the differences in the 2010 27 inch and the 2011 27 inch are worth the difference in cost. I can get a new 2010 I7 2.93GHz for $1588 while the 2011 cost $2198. The main differences are 2.93 GHz vs 3.4 GHz cpu, 5750 video vs 6970m and no Thunderbolt on the 2010 model. Is the 2011 iMac worth $600 more? My uses are general use, some Real Studio programming, Carrara animation and rendering, Light gaming. Nothing to heavy.
