Just bought a 1060 3gb it's on its way. Now I currently have a Nvidia GeForce GTX 730 2gb.

Solution
graphical drivers only worry about the GPU core itself which is always Nvidia. Gigabyte, EVGA etc etc don't make the GPUs. Just the coolers and some of the PCBs.

I'd recommend uninstalling, as mentioned above, the nvidia geforce drivers and reinstalling them.

Kasper Jorgenson, do you mean YES I can simply use Nvidia experience to upgrade my driver's? I also need to know, do I HAVE to remove all my previous drivers for the 730? And if so... How do I do that?
