The Y50 is a better laptop for gaming.
If you have the the time, can I ask why?
860m is a better mobile GPU than the 840m by quite a lot. And the CPU of the Y50 is much faster than the CPU of the other one.
In terms of aesthetic, the Y50 has a much more gaming look with it's red backlit keyboard. Although the Y50 screen is smaller than the 2nd laptop, I'm pretty sure you can make do with its screen size.
That's about it.
