i have an i man 24.inch 3.06ghz and i decided to give it to my wife so i went out and bought a new mac pro 2.26ghz 8 core.i seems to me that the final cut express rendering is about the same and the performance seems close but the programs never max out my cpu usage so i feel that fce and some other programs are not taking full use of this awsome computer. whats going on?
