I have 8600 GTS and GTX 570 and tried to run both at the same time connecting to 2 different monitors. I want to buy 3rd monitor to conect 1 monitor and 1 TV to GTX 570 and my old monitor to 8600 GTS. Will it work? I've heard that to run 3 monitors (1 being my tv) you need 2 GTX 570 cards in SLI... Will 1 GTX 570 (running monitor and tv) and 1 8600 GTS (running old monitor) be able to run 3 monitors at the same time or the only option is to have 2 GTX 570 cards?
