the gtx 1060 should be plenty for adobe software and a modern laptop.
Do you think that getting a 1070 over 1060 in a laptop would provide any benefit?
according to puget system review 1060 1070 1080 the 1060 seems quite a bit slower in 1080p,
BUT thats with three times faster i7-6950x processor then the laptops 6700HQ,
bottom line is, would the i7-6700HQ processor will be the bottlneck for 1060? or 1070 can provide a substantial boost in 1080p? especially on scrubbing/playback

it would depend on what is being done exactly, but for most premiere projects i would think that the laptop cpu would bottleneck before the gtx 1070 will be of use. like you pointed out, the 6950x is 2-3x faster than the laptop cpu, so the results from that article aren't going to translate to a laptop setup.
I am quite happy with my laptop with an i7-4700HQ CPU and a GTX 765M. So I see no reason why you would not be very happy with the GTX 1060 with more cores and more memory bandwidth. But here is what you do, overclock the GPU Memory Clock to get a free major boost in the GPU performance. I am absolutely delighted with my GTX 1060 in my i7-5960X @ 4.5GHz which is running very conservatively at a Memory Clock speed of (GPU-Z) 2400 MHz some tools show 4800Mhz and nVidia uses a virtual 8 Gbits/second which I am exceeding with my 9.6 Gbits/second.
I hope you realize that any laptop really requires external power to do decent editing. On battery power-only the slow everything down to achieve longer battery operation. Timelines like my 4K XAVC-S 100 Mbits/second on my laptop that work perfectly with no loss of frames on full resolution playback lose many, many frames when I pull out the AC power connector
there's a good deal for second hand laptop with i7-4700HQ and 870m gfx card.
i wonder if yet again, if the i7-4700HQ CPU wont be the bottleneck of 870m for video editing?
its 40% cheaper then a new 1070 laptop, i plan to edit 4k.
....I have the same laptop as Bill. The newer 4 core i7 CPUs in laptops do not offer much performance gain over our "old" 4700HQ CPUs.
Our laptops are a little "limited" by our 765m GPUs that only have 2GB of DDR5 video memory.....4GB is better for use with 4K editing....I would look for a laptop with at least that much NVidia video memory.
