A $1k laptop is going to be on par with about a $600 desktop build. Like this:

No laptop that exists as of now can touch this in gaming performance (edit: unless you want to spend north of $3k):

There are lots of options in between, but if you must get a laptop I recommend the Acer V15 Nitro as most for your money in your price range that are lighter and thinner than most, as well as reliable. Newegg has them in 15.6" and 17.3" versions for both under $1k which will be about on par with the $600 build I posted in terms of performance.
