I don't think there are any good choices.
The only 16:10 notebooks I'm aware of are the XPS 13 + XPS 13 2-in-1 (much improved internal graphics, but only light gaming possible), the LG Gram 17 (not gaming), and the Apple Macbooks (only the Macbook Pro 16 has a decent graphics card).
Other candidates with a tall aspect ratio (3:2 instead of 16:10) are the Surface Books, the 13" has a GTX 1050 and the 15" has a GTX 1060.
Overall, the most sensible buy of these is probably the MacBook Pro 16, but that's still paying a hefty price for mediocre gaming power.
