everyone is forgetting that the GT200 will fight the 4870X2
lets assume a single 4870 is 50% faster then an 3870 (50% more shaders, 50%more TMU, higher shader clock, high speed DDR5)
A GT200 would be twice as fast as a single 4870 (300% / 150% = 2)
So it will be equally as fast as a 4870X2 (F@H scales quite linear)
i dont realize how this is such awesome new?
