worth or not...
it is up to you. For my case, my D70 + lens cost like 2k. I feel that the $480 you spend on a copy of PS will have as significant effect on your photos as a $480 lens upgrade. I mean with better noise reduction, you can afford to shoot at higher ISO, the workflow of PS CS is also MUCH better than the iphoto I was using.
+ healing brush, clone stamp, magnetic lasso, raw photo editing, batch actions, etc.
