quadro p1000

I am putting together a PC build and have the ROG Crosshair VIII Dark Hero Mobo with AMD 5900x CPU. I will be using 8 monitors on this computer and need to install 2 Nvidia Quadro P1000 GPU's. My question is, do I need to use a SLI Bridge to connect the 2 GPUs or can I just install the 2 GPUs...
