Hi, New to the forum really and I could do with a little help from all you guys that know your stuff. I'm thinking of buying a 27" iMac in a couple of days. I will either buy the new one for 1399 squids or a refurb from 2009 which is cheaper on the uk website. What do you guys think I should go for. The refurb is a couple of hundred cheaper. Will I really notice any difference in performance. I wont be playing games. Heavy user of films and YouTube etc that's all. Downloading of music and film also. Any advice would be appreciated. Anyone experience of both?
