I'm really torn between which to get...I'll be using it for web surfing, some light photoshop stuff and I'm majoring in computer science, so some c++ programming (most of it being done in the terminal). I wont be doing any extreme video editing. It would be between a dual 1.8 powermac or the 1.8 iMac (probably 17 inch due to lack of desk space). Im leaning towards the iMac because I can get so much more for less. Hell, right now my G3 iBook is able to handle everything I've mentioned so far, so Im thinking a powermac will be too much. Will I notice that much of a difference with only 1 processor and the slower bus speed? thanks
