Maybe someone can answer this for me:

does Nvidia have cards w/ two DVI ports + HD component out and all ports active at the same time? Maybe something like the Quadro 1500?

I see they have the outputs, but are they all active at the same time? In other words, does this card (or another like it) have 3 monitor capability, one being either DVI or component?

I am thinking of getting a Matrox Parhelia for that capability, but would prefer the better GPU power of the Nvidia cards for using with Serious Magic's Ultra 2 for chroma work.

here's a thread at 2cpu that might interest you:

I have a Nvidia 7800 GSOC AGP card and a Nvidia Quadro fx560 with video component out hooked up to my 37inch westinghouse. I have all three running at the same time. But it took 2 videocards. to get 3 displays.
