Good Graphics Card, Slow Render?

Ram: 16g
GPU: Geforce GTX 1080
Processer: Intel® Core™ i7-6700k CPU @ 4.00 GHz

With so little information, it’s impossible to say what is wrong. Provide a blend file and people stand more chance of pinpointing the problem. At the very lest, provide a screen shot of your render / output settings.

show a pic of your blender system settings. make sure the gpu is enabled, you have to click it and it turns dark grey for on.
