myway and shirogawa are recommending some good alternatives for you.

A GTX950M isn't really good at gaming. It is the entry level for mobile gaming graphic cards. You should only choose this if you're gaming on a tight budget and your games are mostly clone MMORPGS from Korea with anime/cutesey kind of graphics.

the GTX960M is far superior to it but sadly is getting beat up by 2016 games. Still, you can go full HD with med-high graphics options on this model. A safe bet if you're into gaming but don't need to max out everything.
