I have no doubt that nVidia designed a god awful, complex, gigantic, needs it's own power plant GPU that is sure to beat the 5870. Of course how many of them they can make and if it can actually compete with the price point of the 5870 is yet to be seen. Of course since I haven't heard of the G300 launching any time soon I'm sure the 5800 series will enjoy some time at the top.
