I've got the AMD64 3200+ your looking at in my mythbox and at
1920x1080i I get around 60-80% cpu usage depending on the channel I

HDTV unless I use timestretch or if I mess with the OSD a lot... this
is with deinterlacing on (any version of it, bob, kernel, etc.). I am
using freq scaling to downclock the CPU to 1k when I'm not using it as
well, it seems to work very well.
Doing HDTV with the dual-core 3800+ would probably be pretty nice,
it'd probably leave a lot of overhead avaiable for crunching stuff in
the background, which leads me to a question. The dual-core are still
939pin right? Are they swappable with any 939 mobo, or does the mobo
have to support the dual-core chip?

I was going to get this:
AMD Athlon 64 3200+ Venice 1GHz FSB
Until I saw this article:
http://www.extremetech.com/article2/0,1697,1893821,00.asp
suggesting this:
AMD Athlon 64 X2 3800+ 1GHz FSB Socket 939 Dual Core

dual core are 939 pin. They are compatible with virtually any recent
939 mobo (supposed to be with all). This is mainly because the chip
itself mainly interfaces with the motherboard in the same way as a
single core 939 cpu. The dual channel memory bus gets split by the chip
into a single channel for each core if I remember correctly.
So have no fear in upgrading your 939 board to dual core.
Still, I hate that extreme tech article (nothing against them); they
built a ridiculous windows mania hardware schmorgasbord, complete with
two uneeded external boxes tethered inelegantly to their nice HTPC case,
all for only $2300, ugh.
