1 year isn't long enough IMO. That's a small pile of cash there and you want 2 years or more.

As to the 960m, it's a respectable GPU (I have a gamer laptop with it.)
http://gpuboss.com/gpus/GeForce-GTX-960M-vs-GeForce-GTX-1050-Mobile shows the 1050 is a notch up but nothing like the 1060 mobile.

If you are a gamer, why not remove the 960m?
