I currently at home have a G4/400mhz Tower....I know, I know...but it works good for my CS1 Apps and the Internet. I work in Prepress and am so use to working on Mac Pro at work 2.66Mhz with 8G of Ram....Using CS4 flawlessly with no crashes ever....not like at home. Im looking for the iMac 27 for Home Use.....and am on fence for either Core 2 Duo or the Core i5....I will be using Adobe CS4 (Indesign, Illustrator & Photoshop) primarily and dabbing in with either Final Cut Express/Pro or Adobe Premier. Is there a big difference using CS4 from a Mac Pro vs iMac.....as for Video is Core 2 Duo fine or should I go for Core i5. Thanks for any advice!!!!
