External graphics card on alienware

[Overlord_NT]

Hello,
My laptop is an alienware m14x 3rd gen with 16gb ram and a Intel core i7-3630QM but the graphics card is only a nvidia gtx 650m my question is:
Is it possible to attach a stronger external video card such as a gtx 960 and if it is how would i do it? Thanks for your help
