Google up Notebookcheck 940m and then the 950m
The 940m uses DDR3 and the 950m gets a higher performance kick from DDR5.
So that alone splits these into very different machines.
Most of your links are messy smartphone views and I can't find exact models to dive into. But given the 2 GPUs I dug up my nod is the 950m will win by performance alone.
Laptop is gonna be used for creating and playing around with gopro movies. Also my wife is interior designer so photo shop and that kind of graphic design software, thanks.
These r my options, i am convinced strongest by lenovo but my knoledge is minimal so i need advice, thanks
