This comes from where http://forums.anandtech.com/me...=2149352&enterthread=y left here is how i heard it stright from Ajay (A tester) the 9800 GX2 has a core that not only hotter in temp than the 3870 but is also scores better i bet that you all know that but now something you dont know:-
He told me that the 9800 gx2 slows down when a certain temp is reached.. for example the core in the bottom (which has a higher temp according to ajay) will slow down from the real clock speed to a safer speed so that the bottom core has a lower temp. but this will give it lower performance....
So as per Ajay the 3870 X2 has a advantage there as all core are on the same silicon but he says that the advantage is really pointless as in some months a new nvidia card will come and right now 8800 high end cards can give the 3870 x2 a run for its money/....
