Don't know exactly. My backend box is a core 2 quad, and I have all
commflagging done there.

iirc, the 45w sempron is clocked at 2.7GHz, so it ought to smoke an
Athlon 3100+ for commflagging, and probably does do faster than real
time for a single mpeg2 HD recording at a time (don't really know for
sure about mpeg2).

Don't know of any offhand, but there are some boards out there still
with nvidia geforce 8200-ish class graphics that will take these
chips. My main[1] frontend is currently a 65w dual-core athlon x2 on
an amd 785g (iirc) chipset motherboard with amd something graphics
onboard, but I use an nvidia gt220 video card.

[1] the "main" frontend doesn't actually get used nearly as much as
the secondary one, which is upstairs, where the kids watch stuff most
of the time, especially during the summer when the myth box has very
little to record. The secondary frontend is an asrock ion330 pro right
now.
