I currently have the 1st generation Macbook, which is the 2.0 GHz Intel Core Duo model. I upgraded my macbook to the max with 2GB of RAM as well as 320 GB Hard Drive. What I'm doing is heavy photoshopping as well as full HD video editing, so obviously it lags big time. Since it's more than three years old, I decided to get a new mac, but I need some power. I'm looking into the iMac, but I'm hearing rumors about some major updates. I need a new mac now, because it's crapping out on me, but I want to wait for the major updates. Any suggestions? Should I wait? When do you think it'll be out? Also, what kind of model do you think is perfect for what I do? 3 GHz? Thanks.
