Got the driver and tested 3d Mark Port Royal on my 1080ti. It was definitely not playable (so to speak) at around 12 fps average but that isn't my main concern.
My main concern was that while the reflections did look ray traced the shadows and other elements didn't and there was an overall fuzziness to the images. I understand that currently it's an artifact of the fact that not enough rays can be traced per pixel, but I would say except for the reflections you could have achieved similar results with traditional rendering.
Still, there's no denying it that eventually ray tracing will surpass rasterizing in all aspects but we're just not there yet.
PS: Waiting for a ray traced remake of Crysis to happen so that we can all ask 'But can it run Crysis?' again.
