Nvidia has just released their new version of forceware 84.12 drives, & purevideo codecs, which finaly enable the long awaited HD Video decoding capability, on any media player, which supports H.264
the 3 main media players which will benifit from this is Nero showtime, WinDVD 7 & PowerDVD 6 latest, as they are launch partners. Since Quicktime is already using Core video technology to decode the video stream in gfx card, it is also supposed to benifit a lot.
It's possible to decrese the decoding capability upto 50%, even of 1080p video, as long u have good enough clock speed & power in your card. so if u can overclock a 6600GT to 800 MHz core
u can decode 1080p easily, at stock it will decode it but cpu usage will be high still. at 720, upto 50% decrese is expected as shows by nvidia in a recent electronic expo demo
U can download the new Nvidia drivers from here, although these drivers support many gfx card, don't expect H.264 decoding in any gfx card other then geforce 6 & 7 series, that too when purevideo codec is used. This finally gives a reason to upgrade to Geforce 7 series
