I was looking over the specifications of the new macbook and macbook pros, and found they are using DDR3 memory at 1066 MHZ. Correct me if I am wrong, but the memory used in these new laptops is actually faster than in apples mac pro? I am also curious about the speed difference between mac pros, imacs, and the core 2 quads inside dells desktops. How fast are our mac pros in reality?
