Does there exist a video card that has Mini Display out and is compatible with the original Mac Pro? I had a 23" cinema display that was repaired by Apple and then manhandled by UPS (multiple times, actually). Apple is sending me a new 27" LED display. My computer is the original Mac Pro 1,1 with an nVidia 8800gt and as of right now, I have no way of connecting the two. I would like to just upgrade my video card to one with mini display. I have heard that the converters are either unreliable or don't work at all.
