Ok so for some time not I have been looking at the possibility of 3 monitor display in horizontal mode for gaming. The only thing is how would i go about setting something like this up? I would like it for intense gaming and would not want the monitors picture to be starched. If i sli 3 video cards from nvidia + One For physics would that support 3 monitors? What kind of hardware/software would i need if not?
Or you could just get one of ATI's new 5xxx series cards. They all have Eyefinity support, which is using 3 monitors from one card. I would get at least the HD 5870 ($400ish) for gaming with this setup. Ideally, you would want the HD 5970 ($650, if you can find them in stock). There's an article on the front page of Tom's (or I think it's still there) about it.
