So, I have an ASUS P8Z77-V LK mobo and on the Nvidia site it is only able to support 2 way SLI. This is fine as I don't plan to go more than that anytime soon, but I'm intrigued by the idea of a dedicated PhysX card. First, would this mobo be able to do that, despite it being able to only support 2-way SLI? And second, what would you think about a 750ti for the PhysX card? And if you think no on the 750ti card, what would you recommend?
