Kyle (in video) was theorizing that the NF200 introduces a small amount of latency into the process, accounting for the slight drop in frames, which is pretty reasonable imo. And really, both Nvidia and ATI probably understand the limitations of the PCI-E bus (1.1 or 2.0) on their cards better than anyone, and have coded accordingly, to ensure that data transfers don't saturate the bus. Thus, even if the NF200 actually worked the way marketing would have us believe, the benefits would likely still be negligible.
