Upgrading Alienware M17x-R4 GPU


May 20, 2015
I burnt 3 GPUs so far in my Alienware but since it was under warranty, so Dell Replaced them. But now my 4th GPU is as well going bad and I experiences Crashes when gaming and sometimes During video watching & I am out of warranty as well.

I was wondering if I could replace the GPU with a Maxwell series NVIDIA GPU GTX 960M since its supposed to be low power consuming and I hope that translates as lower heating issues.
I would Like to know
1) If that is a Feasibility?
2) Is there a way to buy this Part in India?

Any advice would be of great help please.
