Hello. I`ve already chosen the laptop for video and 3d editing - it is Lenovo Y700-15. But, few days ago I saw message in one forum that means: "Almost it is no difference beetwen 4GB and 2GB Nvidia GTX 960m. They have almost the same work speed and etc." This information I saw in video gaming forum. And this computer was seen as gaming laptop. And now I don't know - does it has any connection with video and 3d editing? If there is no difference - computer with 2GB costs cheaper.
