Hi there! I'm going to buy my very first macintosh computer and it's going to be the new imac.. I am going to use programs like final cut,premiere,after effects,photoshop,lightroom,illustrator maybe sony vegas etc...But I'm not sure about which imac i need.. my budget is 2.300 $ max! So guys give me an advice about which one is better between 21,5"/i7/16gb/fusion or 27"/i5(3,2ghz)/fusion.. (I use a 15" screen now and i think that the 27" is very big! also if I'll buy the 27" I will upgrade ram myself at 24gb for now and maybe later 32gb) Thank you in advance!
