I don't want to clone. I want extra desktop space. I have an old PCIe 6600 card, but it won't fit because of my dual-HR 03's.. damn it.
Well, I guess I'll have to fine a way to connect my mouse and keyboard to two computers..
Or you could just, you know, disable SLI when you're not gaming and re-enable it when you are, from the control panel. Unless you must game on one monitor while browsing or watching a movie on another, it's not a big deal. Annoying, yes, but not a deal breaker.
you could try a matrox dualhead2go digital.
you can only hook up your monitors with dsub, but theoretically it should work. it takes 1 output and allows two monitors to be hooked up.
or you could do a triplehead2go digital and hook up 3.
I have no idea what kind of performance you will see from it, but you could try.
