Laptop for video editing


I am writing this for a friend, he is going to study abroad and is looking a for a laptop to take with him. He mainly will use it for video editing (that is what he studies). His budget is 1500 +- dollars. I think apple is not a option cause they are more expensive so lets get only into windows laptops.

The main spec that it should have are an quad core i5 or i7 processor and a dedicated gpu.

So please guys help me so I can help him :)
