I'm going to get an Asus Maximus VI Hero, but i want to know if there are any z87 motherboards that support 3-way SLI, all I can find are 3 way Crossfire and 2 way SLI. Is there a reason behind it? why are crossfires getting 3way and nvidia only gets only 2 way? I know there are x79 broads that get them but no z87.
