Depending on what threads myth is
using, and how, you might find that playback is WORSE with the 3800
X2.  A simple test would be to playback 1080i now, and run 'top' on
the FE machine.  If you only see a single "mythfrontend"
process in the top 10, then hit "H" (capital) to tell top to
show threads.  If it's a single thread thats eating most of the CPU,
then having 2 cores (each slower than your 3700) won't help.  If it's
multiple threads each eating about the same amount of CPU, then the dual
core might help.

As a side-note, on my machine (X2 3800) I got
choppy playback if I turn off XvMC and leave bob deinterlace on.  Of
course, other deint filters might eat less CPU...
