I've run MythTV on a GF2 card but not since 0.16 or so. The card will
work (and with S-video) but there are a few caveats that may or may
not still be valid. For one, IIRC, the GF2 would not display properly
until X started. This may or may not be a great concern, but you'll
need to have a monitor handy to do the inital setup and X

I wouldn't count on the GF2 doing OpenGL, but it may be possible. When
I ran a GF2, it was able to handle the Goom visualization in Mythmusic
but only at 1/2 resolution. I'm not sure if it was because of the card
or the system I was using (P-3 750) or a combination of the two.

In any event, Myth will work with qt, and the GF2 should work as long
as you have no illusions about OpenGL or other 3D gee-whizzery.

I'd say it's certainly worth a try to get your system running with it
before you buy something else.

Use the cash you save to get a bigger HDD. That's the first thing
you're going to want.
