After reading up on the Nvidia drivers some, I discovered at least one issue. The Linux kernel command line for my installation had nomodeset included, which according to https://wiki.debian.org/InstallingDebianOn/Dell/Precision%205520%20%28Laptop%29/jessie will cause problems. Once I removed nomodeset from /etc/sysconfig/grub and then ran grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg since I have an EFI system (See Fedora Wiki: Grub 2), GDM no longer crashes during start up when I have the Nvidia proprietary drivers installed. In the end I believe that this actually allowed the Intel drivers to load properly, which were apparently important for GDM (and Gnome 3) to run using Wayland.
