mantra

Hi, I have a question and hope that someone of you is able to give me an answer... I own a Lenovo T440p with GF730m which is "a bit" underguned for todays gaming, so I´m in the ring for a solution. As far as I understood this thread, it may be possible to go with a egpu via m.2. Does anybody know if that´s possible wiht my notebook? Thanks and regards Robert
