I want to get an iMac, I went to the Apple Store and they had a retina and non retina right next to each other and honestly I wasn't impressed with the retina, yah the colors are brighter but is it really worth the extra money. I love nvidia cards and have had problems with AMD in the past, I know no one knows but Apple but should I wait and see if there is a new non retina (or even retina) with the new nvidia chipset in it? Or should I get one now, I hope to get at least 5 years out of it so I want to make sure what I get will last, I will be using it for Adobe suite, and CAD design for my college work as well as some light to medium gaming and day to day tasks such as web surfing.
