It's actually plenty with a card that spits out MPEG2 already. I'm
running a similar setup with debian on a celeron 466, here is a snapshot
of top while it's recording....

It's also quite fast enough so that I can watch something (via samba or
http) while it's recording. You can see that there is a fair bit of
time spent waiting for disk IO (35% or so). Make sure that you have a
fast disk and it should be fine.
I don't think you need the full QT stuff on the system to run the
backend, maybe just the QT libs. The debian package deps would tend to
indicate that is the case.
