Thanks Dave. I had found a similar article on xbitlabs about Radeons,
but hadn't seen this one NVidia cards. Unfortunately, it's from 2004
and only covers the 5000 and 6000 series of cards, which you basically
can't buy anymore. Odds are the card I'll get will be something in the
7000 or more likely 8000 line given their widespread availability and
low prices now (There seems to be a decent amount of 7300 and 8400 cards
that are smaller and fanless, which is promising).
The NVidia.com page is interesting, but it has only peak power usage,
not idle and covers only the Quadro series. For a MythTV box, putting
in a Quadro is extreme overkill.
Building a quiet box is a bit of a challenge. I could also add the
requirement that HDMI on the card would be nice as it eliminates another
cable going to the LCD set in the living room, but I think that just
makes me picky.
It's looking more and more like I'll have to just get a new motherboard
like one of these with integrated HDMI and video:
