I am a graphic designer and I want to get a 27" imac. I mainly use the CS4 suite and do some home video editing in iLife. As a designer I am more interested in screen real state and HHD space than game performance that is why I want the base 27" - plus the lower price fits my budget better. Now, what am I missing performance-wise between the the C2D and the I5 processors? I use a 2.4GHz 24" Imac at work and i would not say its slow...although with a little bit more than the 2GB of ram that it has would be even better. As I said before, I am not a gamer I just need something that works great with CS4 and Ilife. Is there a noticeable everyday difference between these two desktops?
