Best laptop for UE4

So, you’re saying that a laptop is not very powerful and it can’t handle UE4 on Epic Settings with optimal performance. Will it reach 50/60 FPS with a 960M 2 GB? Or the video memory is a little bit small? I don’t have any ideas about that.
Anyway, can you tell me a laptop model that you consider able to handle UE? My budget is about €1600 ($1800 US Dollars).
I wasn’t considering the idea to buy a top-tier gaming laptop because usually they are quite heavy and they have general short battery life. Is a “good laptop” meaning a big, heavy laptop?
