17" screen + powerful GPU doesn't leave too many sleek options a la macbook. But if you look towards gaming laptops you'll find plentiful options.

Ubuntu might be a little more difficult, depends on driver support I suppose. Most come with either no OS or Windows.

Here's a search for 17" + 1060/1070 + 4k. I'd probably stick with 1060 to keep some sort of handle on heat management unless you really need more. I've had a good experience ordering from here in the past (Sager NP8660, great machine with an unfortunately large power brick).
