Hello, this is my first post, and I have a pretty small question regarding SLI. To 'hook-up' a second video card to my existing one, does it have to be the same make and model? Or would it be possible to use a different video card with the same GPU and connect them with an SLI bridge? I'm asking this because I have a 6600GT video card that is SLI ready, but I cannot find any documentation for it so far ( :doh: ), and I haven't been able to find anything online that looks akin to it. I'll update this post if I find anything helpful on my video cards make and model.
