The HD4850/4870 have twice the amount of texture units, far more shading power and higher clock speeds so its bound to be atleast twice as powerful than the HD3850/3870, which is still faster than any single nVidia GPU, though the GX2 should still be faster.
Also because the nvidia drivers were "cheated" so that when crysis.exe was run, the GPU(s) would sacrifice image quality slightly for better performance. If you were to rename crysis.exe to something else, the performance on a nvidia card would decrease.
