Which would you pick for your video editing laptop? *NEED AN ANSWER TODAY* :s

[Scotty_Cartner]

Hi Guys!
I have have to make a decision today, which makes things a bit awkward, but I really appreaciate everyones help.
I usually do editing at 1080p 60fps but I am looking to start using 4k video.
I have come across these THREE laptops that might just fit the bill, but I wanted to get your opinion of which you think is best and if they are even worth it?
The first two laptops are over the £900 mark and the third is £750. Am i better off getting the cheaper laptop and add a hard drive or have everything set up for me straight away?
What would you guys suggest? :S

pick the first one Lenovo Y700 15.6

Any particular reason why this one over the others?

Choose the one with the 970m as it is a more powerful gpu than the 960m. It will make a difference in rendering time.
