Also, the ATi benches done by reviewers who use default settings (most) are not at comparable IQ due to ATi's performance enhancing, image quality reducing AF optimizations that have received more and more mention in reviews lately.
Except that PhysX is pretty unplayable without a second card, Forced AO is pretty useless and gives such a performance loss is no use, hardly any CUDA games(again CUDA takes a huge performance drop in Just Cause 2 for example). NVIDIA have a history of AF optimizations as well, reducing image quality or making big gains in benchmark apps.
