So, I wanted a Mac for graphic work. I currently use it have Adobe CS5.5 Design Premium on it, and am hoping to upgrade to CS6. I mainly use PhotoShop, InDesign, and Illustrator. They're the most intensive applications I use. I then use Office, iTunes, Safari etc. I have a few films on iTunes, but not many, and I occasionally watch streamed video. I have the base model 13" Pro, and am going to be upgrading the RAM from 4GB to 8GB, because I can notice slowdown and lag when running iTunes, Safari and Photoshop (when working on images A3+). Just curious, is my Mac enough for what I use it for? Or should I have gone for the i7 2.8GHz dual core 13", or even the 2.2GHz quad core i7 15"? Or will this be enough for me for the next year or two?
