Default Two cards in one box - question

Hi,

Is this possible? A mainboard with two PCI-E 16x slots, one fast card intended for gaming, another low budget passively cooled card intended for VDPAU decoding only.
Can I then run two X servers (or perhaps one is better?) on the cards, running XBMC on one card outputting via HDMI to some device, using VDPAU, while at the same time, playing a game using the fast card, outputting to an LCD monitor?

Or is VDPAU and gaming possible at the same time, using one card and two monitors? (the card has got two outputs after all)

Yes, you should be able to use two cards at the same time. Running two simultaneous X servers (a so-called "multiseat" configuration) is not supported and not recommended, but you can have separate X screens on the two cards using a single X server.

You ought to be able to use VDPAU and play a game at the same time, but please be aware that they will both compete for graphics processing resources, and the game may cause VDPAU to slow down.

But I would have two graphics cards, so there would be no competition for GPU resources, no?

I'm sorry, I should have stated that more clearly. Yes you're right, with two GPUs they should run independently. The competition for GPU computing resources applies only if you're running them on the same card, obviously.

I probably shouldn't post when I have a fever...
