Is it possible to run two different graphics cards simultaneously?

I posted a thread yesterday asking about the hardware requirements of running Media Center on Win 7. I got no answer, which I seem to have a real problem with on this board, so I'll ask the question a different way.

Is it possible to run a different Nvidia card along with my GTX 275?

Current System:

i7 920
6GB Ram
Asus P6T Deluxe V2
GTX 275
Seasonic 850W PS

I am running dual displays off of my 275, so I have no more output ports. I'm getting Windows 7 in a couple days, and I want to be able to pause and record live tv from Windows 7, and I also want to be able to watch torrents (movies, tv shows, etc.) I've downloaded on my HDTV. I'm guessing I just run a USB cable from my cable box to my pc for the input side of t hings, but I need another graphics card to output HDMI to my HDTV.

Here is the card I was condsidering getting: http://www.newegg.com/Product/Prod [...] 6814121320

It's an Asus Geforce 9600 GSO. It's cheap (45 after MIR) and hase a native HDMI output.

According to Nvidias website both my 275 and the 9 Series cards use the 191.07 drivers, so that has to help.

So, my two questions: 1) Is this what I need to do what I'm wanting to do? 2) Will this work? Or will the two separate cards cause problems?

No, you have to use the same model and make card in order to utilize SLI. You'll either need two 275's or two 9600GSO's. The driver's release date has no bearing on whether two different cards will work with eachother or not. With that said, a GTX275 is PLENNNTTYYY to watch and record live TV and watch torrented movies.

You didn't listen to what I said. I'm not running SLI. I completely understand SLI, and I have no desire to run SLI at this point (well it would be fun, but I'm not spending the money on another card). I simply need a second card because the two DVI ports in my 275 are being used by 2 displays, and I need an HDMI output to go to my HDTV to watch torrents and tv that I've recorded on Win 7 Media Center.

I don't need a tuner card because I'm not actually watching TV on my computer. I'm simply using my computer as a DVR, which I'm about 99% sure you can do with a Media Center OS and a USB connecting your cable box to your computer. I could be wrong on that one though.

Ah, gotya. It wasn't totally clear so I assumed you were about to buy a 9600GSO as an 'upgrade' from your GTX275. Haha .. sorry about that.

Yeah, I assume it will work as well. I've seen people do this in the past .. so I don't see why the technology wouldn't carry over to our modern day goods. And the 9600GSO is probably plenty for simply watching movies and such.
