I have the ability to buy an new macbook 2,1GHz or the latest powermac generation with the dual core G5 processor. 900 euro's for the G5 and about the same for the macbook. The G5 comes with 6gb of ram and a Geforce 6600with 256mb of ram.. I will be using it with a 23" ACD and be working with Photoshop files with the size of 300-700mb. What will be faster in both processor en core image performance? I have some doubts about the X3100 and 1920x1080 I think it wil deliver choppy animations/performance.
