So I'm currently upgrading my pc to run 4k and upgrading my windows 7 to windows 10 so that I can utilize it, so my questions are which gpu do you use when in sli? I'm assuming you just ignore the gpu in the second slot when using sli,

Second, to use 4k do you use hdmi or displayport? I'm assuming display port.

Thanks everyone in advance. :)
