S-video out in newer cards?

Quick question.. I would like to build in a near future a decent gamin rig, wich can play playstation and wii emulators, and play crysis, but I want it to have s-video output so I can bring the pc to a friends house and play the emulators on their crt tv´s...the problem its that Im seeing that the dont yet released new dx11 cards doesnt have s-video..so Im out of luck? o

I once had a scan converter but it looked half decent with translucent lines walking horizontally throught the screen.

Maybe there is a cable ? dvi,hdmi,rgb to s-video?

Or can I use 2 video cards at the same time? one cheap for tv out, and the other for gaming? but I doubt it....

Or maybe when there are more dx 11 cards out, some will have s-video...

Thanks, and sorry for the bad English, just in case
