We have a new hd surrveilence camera slated for release soon. I am looking into a high performance video card that will render at least 6 to 7 live hd streams via our client viewer and web interface, Vlc, and quicktime.
Our onboard encoder on the camera does not pass data to gpu but still need gpu for the
rendering side. I'm leaning towards 1) Ati radeon 5970 and 2) Nvidia's new 480 series.
This situation is strictly for rendering live hd video and not gaming but it seems that high video cards are base on gaming for obivous reasons. . Our h264 implementation will be
rendering 30fps, and a bitrate of 4mb.  I will also be ordering a high end i7 pc.
The application is cpu intensive once we start openning multiple streams.
If anyone has any knowledge or experience on these two video cards any suggestions
will be appreciated.
thanks in advance.

Hi proj2005, I'll start off but with limited knowledge on the ATI as I use only Gigabyte  Nvidia. But using the benchtests of the ATI maybe a better choce, use a 64 bit OS that'd keep things very fast and supports a lot of ram 6 gig and more I believe\
Wait a few days till Easter is over and the experts will come back
In the mean time check out PC stats for all the video cards  information you need, I use this sight a lot to compare products

Merete, Thanks for your response. I will definitely check this website. It seems however that
the ati 5970 has quite a few system requirements...I'll have to check it again..
Have u used or know of anyone using nvidia 480 or 470, supposely their newest and greatest?

Well, I would still like to get more feedback on the Nvidia 480 and the Ati Radeon 5970 if
anyone else has more info.  I'm currently trying to submit a work order to order
a high end i7 2.8ghz or higher w/tons of memory....the video card is my bottleneck.
Any info would be appreciated.
