I'm thinking of getting a motherboard with a built in 8200 and adding a 9600. First of all, will they work together?

Also, a lot of the time, I play games in windowed mode so I can watch TV/movies in VLC on the side. Can I set it so the 9600 runs the game, and the 8200 runs the desktop and video? If not, can the 9600 run one screen, and 8200 run a 2nd screen?

Are you planning on running more than one monitor?

Yes, I've read that you can set it so one display is run by one video card through sli, but this is hybrid sli. Will it still work?

Hybrid SLI works only with 8400GS and 8500GT. I am 100% sure about it. Dunno about multiple monitors tho. But I am sure you cannot SLI 8200 and 9600!!

thanks, how about this
Nvidia 9600 + cheap pci card (not sli) = 2 monitors
I would run 3d games on my 9600 monitor and movies on the cheap pci card monitor. Would this work?

I think you can have two gpus, one in each pci express slot. Idk for sure. I was thinking about how running two graphics drivers at the same time would work... I think the two cards would have to accept the same driver. Once again, i'm not entirely sure about that.
Check around on google for hybrid sli and see what it says. Check Nvidia's site too.

Sorry I can't be more of help atm.

I just realized something.

If you buy a hybrid sli board, it will have an integrated gpu that can run the other monitor. You can install your 9600gt and I believe you should be able to use that card and the integrated gpu!

the integrated gpu is supposed to be quite powerful, so you don't have to worry too much about bogging your system down.

Hope this helps.

EDIT: the 9600gt isn't supported by hybrid sli. It's either the 9800 series, the GTX series, or the 8400 and 8500.
