the dual cores are peppier in the menu and loading up MythVideo and
MythMusic, not by a whole lot, but definitely noticeable.

I got the dual cores because I got the systems on sale through Newegg,
who seems to put them on sale at least twice a month. For playback,
VDPAU handles everything, but the OSD fade needs to be disabled or you
get visual stutter, with the single core getting occasional audio
stutter as well for higher bitrate streams.

I get the feeling that, by the time 0.25 comes out, you should be able
to get a 230 (single core) based ION system for even cheaper.

all my commflagging is done by my backend which is a Pentium E2160 and
plenty fast to flag a couple streams real-time. transcoding I don't
really use myth, so I can do it on my backend or my laptop.
