    I heard that people are using RX 460 and GTX 1060 together for the performance and AMD's techs. So I wonder if I can use RX 480 and any Firepro gpu card together or not.

    Technically, you can install any supported cards in the cMP as long as you can manage how to power them.

    How can I use both GPUs together for a monitor?

    I have a GTX780 and a GT120 in my cMP. I have no issues running both. I have two monitors on the GTX780 and one on the GT120. The GT120 is a mac card so I can get the startup screen. The GTX780 is a PC card.

    I never gave it any thought - I just plugged the monitors in and have never had any issues.

    No, you cannot (at least for most operation cannot). For compute (e.g. OpenCL), some software can utilise both GPU, but I don't think that's why you want 2 different GPU in a single a machine. For something like 3D modelling, cannot, only the GPU that connected to the monitor is working. Of course you can connect both GPU to a single monitor, and switch the monitor's input source to utilise different GPU, but I don't think that's what you mean "use both GPU together".
