It still makes sense to use the nVidia driver even if you don't use
VDPAU.  I use an 8400GS without VDPAU and the nVidia 340xx driver.  As
you say, the CPU has to be fast enough, but my 10-yr old Core2 Duo E8400
is sufficient (even for 1.5x audio stretch of 1080i MPEG-2, as well as
1080p H264 Bluray).  If I use the nouveau driver, playback is not as
smooth.

I used to have a 6600 in another system with the same CPU and
motherboard and I think I got similar results -- good with the nVidia
driver, but not with nouveau.
