Need a GTX 1060/70/80 mxm for my p775dm3

Hi guys,
I have a p775dm3-g model with 7700k and a busted GTX 1080. I am in a dire need of a GPU. Any help will be appreciated.

Thanks

If any of you faced the bsod error video tdr failure nvlddmkm.sys and was able to use GPU afterwards please let me know as o tried everything in my power but it didn't work.
I have tried to re-install windows multiple times from scratch still the problem persist that's the reason I suspect my GPU is busted.
