It's worth to check Wikipedia about various chipset generations:

http://en.wikipedia.org/wiki/Nvidia#Graphics_chipsets

I have in my desktop computer a 7600GS (with a nasty small heatsink and 
fan), the passive cooled version (Asus, etc.) would be quite suitable 
for a HTPC. It has quite good 3D gaming performance as well.

I wish nvidia released Linux support for MPEG-4 HW decoding for pure 
video chipsets (6xxx and 7xxx).

In xine + vdr plugin

xine --no-splash --hide-gui --fullscreen -Dtvtime:method=use_vo_driver 
-V xxmc -A alsa vdr:/tmp/vdr-xine/stream#demux:mpeg_pes

or xine + xinelibout

xine --no-splash --hide-gui --fullscreen -Dtvtime:method=use_vo_driver 
-V xxmc -A alsa "xvdr://127.0.0.1#nocache;demux:mpeg_block"

In vdr-sxfe

vdr-sxfe xvdr://192.168.1.4 --lirc --audio alsa --video xxmc 
--fullscreen --post tvtime:method=use_vo_driver

But I have some problems with sxfe, the nvidia OSD color hack 
(video.device.xvmc_nvidia_color_fix:1) is not available. Also the 
playback is not smooth when OSD graphics is active. Perhaps the 
sudo+renice -18 trick from this mailing list today could help.

At the moment fresh CVS, X.org 7.0 and latest (8774) nvidia binary drivers.
