hello! I have an asus z170-a mobo, which can support 2 way sli (which I'm going to set up next week once my other card get here). However it has a third PCIe slot. I was curious if it's possible to put an old evga 750ti from my old PC in that third slot, just for the sake of tinkering. Would it provide any benefit? Or is it not even worth the hassle. Would there be any conflicts with the sli? This is the first time I've ever tapped into sli.
