This is my first question/post on Blender Stack Exchange, please forgive mistakes.

I recently run the Blender BMW GPU Benchmark in Blender 2.79.

My PC specs are:

 - 64gb of DDR4 Ram
 - i7-8700k
 - GTX-1080

The scene took more than 3 minutes to render, however other people around the internet report a render time of 1 minute or less for the exact same scene on the same graphics card.

I searched the whole internet for a reason or solution for the long render time, didn't find anything though.

Maybe someone here can help me.
Any help is appreciated ;)
