Not the OP, but I had a similar deal with a Lenovo P50 during their black Friday sale, 1k USD for 15" quad core i7, discrete graphics, and 256 SSD. I've never seen the OPs price point except for vendors like Sager.
15" is usually easier to find deals on. And to get the SSD included. I am spending $100 to get an M.2 Samsung 850 EVO 250GB. I'm willing to do refurbished and previous generation CPU/GPU, which gets me most of the performance for less money. If I was more into gaming, I think the newer Geforce would've mattered more to me.
