I have been doing some research on buying my new mac and have been looking at geekbench. One thing that I have noticed is that I don't really understand how the geekbench numbers affect photoshop performance? Is there a direct correlation between the numbers and photoshop performance? For instance I am considering a 6-core Mac Pro because I have heard that it is very fast on photoshop, even faster than the 12-core machines! However, the 12-core geekbench score is much higher than the 6-core machine.. So I am trying to get a feeling of how the iMac i7 compares with the lowest end Mac Pro and the 6-core Mac Pro in photoshop?
