So Nvidia cards seem to do worse than the Radeons.  I wish they had
tested other than $300 graphics cards.  You aren't buying one of
those cards to do MythTV, after all, that's strictly for the hardcore

Note that even the NVidia that "failed" were compliant to 140mhz.
HDTV resolutions aren't using nearly that much.

I wish I could get an answer before taking back my TV if it's bad
DVI from my Nvidia.  Though since Powerstrip was able to make it work,
probably not.
