Indeed, it looks like a nice one. I just wonders if the quality is
very good on the third output since it uses a dual-dvi cable and
then a splitter cable. If you want 4 outputs, you still need
an extra PCI card.
Nowadays, Nvidia cards also improved a lot their video quality
on the GeForce4 line.

The quad output card, Quadro4 400 NVS, is a PCI one (in fact, I think
it's 2 dual-output chips on the same card). However, they have plenty
of dual-output for AGP.
This document clarifies (?) a bit the situation for the Quadro cards:
