CentOS 7 does not currently support Nvidia Pascal GPU's out of the box so if you are running into issues with the graphical installer then it's a safe bet that it's because you have a Pascal card in your machine. You can work around this by using the text-based installer but partitioning isn't as full-featured so you might be forced to use the automatic partitioning option.
Once CentOS is installed you can simply download the proprietary Nvidia drivers - which work quite nicely I might add - and be up and running with your desktop in no time. As long as you know how to navigate the commandline until you get the proper drivers installed then it shouldn't be much of a challange.
I have a GTX 1080 in my workstation and the graphical installer hung while systemd was initializing. You'd think at least VESA graphics would work on Pascal GPU's but it doesn't - at least not currently. Hopefully the CentOS installation disks will be updated at some point to at least include rudimentary GTX 10XX support.
