You can do one of two things , either you can e-mail those markings to Nvidia tech support or you can remove the fan/heatsink and see what is on the gpu for identilying markings , it will usually give you the gpu make and model stamped on the gpu.
Or you can do a Google search;
What's a stereo connector? Could you mean dual monitors, as in you are referring to the second DVI port? Or are you referring to the S-Video port? Not having one or both of those and having one DVI out does not mean it has to be a different card.
Oh, and try GPU-Z like everyone has been saying. Its the only REAL way to know for sure.
I can't use gpuz since mobo is dead. The stereo connector is the little circly thing evolve the two dvi ports. Yea my explanation is bad, I know.
I think it's what does 3-d.
It's not a "stereo" connector, and it's not for 3-D.
I think you mean ABOVE the dvi ports not evolve. It's probably a S-video out, could also be used for a break-out box for more connections, but it's probably S-Video. I have seen cards with a wireless connector for 3D glasses that use a connection to the video card, but the only ones I have seen like that was on a SGI workstation.
