The nVidia 93.71 drivers released today help a bit. I was seeing about 88% CPU usage for 1080i playback on my 6600GT with the 92.91 drivers, and with the new drivers I see about 65%. So if you want to run newer drivers for games, PureVideo, etc., these drivers are a little better.
However, they still are not great. I expect that if I rolled back to 84.21, I would be in the range of 25-40%. That's what I get on a similar PC doing 1080i Fusion playback with an ATI 9800 Pro.
