[mythtv-users] Celeron processors with MythTV

[Alan Snyder]

There's a nice article on Tom's Hardware Guide about the Celeron 2.0 (the fastest when the article was written).  They hated it for 3D games because the performance was so far behind the same-cost Athlons, but found that video and audio processing is dominated by clock speed and therefore the Celerons did quite well.  The bottom line is that you should be fine, and the same-speed Pentium should be significantly but not hugely better.

with a 2.4GHz Celeron. When recording 480x480 MPEG4 with increased 
quality settings from default AND playback of pre-recorded show I have 
55-60% idle. I also have to BT tuners and can record both without 
noticed (yet) drops. I haven't tried playing a show while recording 
two, but should be able to since playback only takes 3-5% CPU.
