I think the VERDICT nails this one.

"Verdict
MSI GS70-2PEi71611MSI GS70-2PEi71611
The experiment failed. MSI's new GS70-2PEi71611 can only be recommended to gamers who willingly give up decisive fps for a lower weight and slim build, and are satisfied with lower settings in many games than other comparably configured laptops would render smoothly."

The GE70 Verdict is better IMO.
