Hi everyone, I had a first generation intel imac 2.0 core duo (not core 2 duo) since 2006. Well now I am in the market for a new imac but I'm trying to figure out whether I should go with the C2D or i5/i7. I use my imac for audio recording and it has served me well. Although its age is showing which is causing me to find new creative ways to stretch its CPU power, I wonder if a 3.06 GHz is a good enough boost (from my current 2.0 Ghz). I know most will say that i5 / i7 are better, but I wonder if the significant jump from 2.0 to 3.06 can suit my needs for another 3-4 years. What do you think?
