Ouch, there probably is something worse you could use; but, I'll be
jiggered if I know what. A decent sound card like a Turtle Beach
Santa Cruz would be better. (Or even better yet would be some of the
MOTU stuff - if you can find drivers.) Motherboard sound picks up all
manner of noise from the circuitry around it. The plugin cards have a
better chance of a clean signal. And an external sound arrangement
such as a MOTU 828 Mk 3 can give exceptionally good sound. But that's
an expensive arrangement. {o.o}

Note that there is an input level mismatch between PC sound cards and
professional mixers. You might stick in a 12 dB or so attenuator in
the feed to the PC. And be VERY sure you are using line in rather than
microphone in.

If I had to make a guess your budget is not sufficient to do the job
adequately if you are thinking of fighting motherboard sound. You can
expect sound synchronization problems and noise at the very least.
You'll have to resample the sound in editing for your video to get good
synchronization over an hour or so.

(The budget for the sort of toys I work with is closer to the $10k to
$25k range. So I won't try to sell you anything, especially here. {^_-})
