I'm using a PCI Geforce4 MX440 on my combined FE/BE.  It works fine
and doesn't have a fan, which is another nice thing.  The nvidia
driver does support hardware decoding (by enabling XvMC) with it,
which significantly reduces the CPU load.  However I don't use the
hardware decoding because:

1)  It's extremely jittery when overlaying the on screen display.
2)  My AMD XP1400 (1GHz) CPU is easily capable of decoding standard
definition video in software while simultaneously recording from both
of my DVB cards.

If you have a low powered CPU, tuner cards with software encoding, or
you're looking at high definition output then you may the XvMC
