Hello! I live in Dubai and we just got the new iMac's here I'm confused as to what the minor differences between the old and new and do they make a big difference? I use it mainly for Adobe Photoshop/InDesign and high-res work in Illustrator that can slow down the computer. Does the i3 i5 thing make a big difference? If i get the cheapest one (below)it'll do the trick? The middle models both are the same price The price difference between cheapest and middle is about $270 american) My choices: Cheapest (Dirhams 7000) 3.2GHz Core i3 | 4gb RAM | 1 TB harddrive | 512MB ATI RADEON HD 5670 Middle (Dirhams 8000) NEW MODEL 2.7GHz Core i5 | 4gb RAM | 1 TB harddrive 7200rpm | 512MB ATI RADEON HD 6770M Middle (Dirhams 8000) 2.8GHz Core i5 | 4gb RAM | 1 TB harddrive | 1GB ATI RADEON Thank you for your help!
