I have a chance to buy two used iMacs, both in mint condition. First one : http://www.everymac.com/systems/app...inch-aluminum-mid-2011-thunderbolt-specs.html Comes with 8Gb of RAM, no extra software. Price : €1100 (about $1400) Second one : http://www.everymac.com/systems/app...e-i5-3.6-21-inch-aluminum-mid-2010-specs.html Comes with 8Gb of RAM + 2Tb HD !! (BTO) + Final Cut Pro + Logic Price : €1000 (about $1250) I'm not too concerned about the difference in processor performance, and both iMacs can be upgraded to 16Gb of RAM. I need a big HD so both should be fine (the 2Tb in the mid 2010 model is mouth watering) There is, however, a big difference in graphics performance. The mid 2011 model sports a Radeon 6770HD (512Mb GDDR5), the mid 2010 has a Radeon 5670HD (512Mb GDDR3). Now I now that both graphics cards completely destroy the Radeon 2600HD I have in my current iMac but is the difference between the 5670 and the 6770 really that big ? Should be a no-brainer seeing the price difference is only €100 ($150) but I'm not sure the seller will let it go for that price. For comparison : the new base iMac costs €1379 in Belgium ($1760), without a superdrive + I still want to be able to run SL. So, which one should I go for ?
