Multi Monitor Display

Hello,

I would like to bring up two topics in this post...

First, I have an ATI x1300 pro video card. it has DVI, VGA, and S-Video outputs. so far I am running dual monitors. If I hooked that S-Video output to a TV, would it then become a third monitor? Also, if I were unable to grab a TV, but had a DVD Player and hooked that up to the S-Video output, and then hook the DVD Player to cable, would I be able to watch TV from one of my dual monitors?

The second topic would be about holding multiple GPU's in one motherboard. I'm using a P5K Deluxe mobo, and it comes with two PCI-E slots. One being 16x and other being 4x anyway... I want to get a new video card (x2900HD); if I were to plug that into my main PCI-E slot, then move my x1300 to the other slot (not trying to do crossfire obviously) would there be any driver issues, or issues in general? Also, I would like the freedom of being able to run 4 monitors after doing so. Is that possible?

Oh yeah, and as a side question, would I be able to set them up like this?
