Hello. As most of you know, Apple offers the Xeon W3680 as an upgrade option for the new Mac Pro. It seems that both W3680 and i7 980x are running at 3.33 GHz (3.6 GHz in the case of Turbo Boost), has 12MB Level 3 cache and perhaps operate at memory speed 1333 MHz. Besides these two points, what advantages can we get in choosing the Xeon? I don't compare the X5650 and X5670 with the i7 980x because their clock speeds are slower. I understand that the Xeon requires ECC memory and branded as more reliable for critical applications. If I do not need ECC memory nor run critical applications, is there a point in getting a Xeon system? Is it possible to build a dual i7 980x Hackintosh?
