Hi, I'm currently looking towards buying an imac as a home pc. I will be using photoshop and editing some go pro videos apart from regular browsing etc.. The sales person bas recommended the 21.5 inch model for home use, and the 27 is out of my budget anyway... I need some help in deciding between two 21.5" models which are basically selling at the same price: Either go for the late 2012 2.9 Ghz model: http://www.amazon.co.uk/Apple-IMAC-MD094-GEFORCE-GT650M/dp/B00AF82BKO Or else go for the 2.7Ghz 2013 model; http://www.amazon.com/Apple-ME086LL-21-5-Inch-Desktop-VERSION/dp/B004YLCIC4 Any suggestions would be greatly appreciated. Thanks a lot!
