Nice!
A feature request: I'd like to be able to filter by graphics card. Specifically when I'm looking for a gaming notebook I will probably want a GTX 970, GTX 980, GTX 1070 or GTX 1080.
Totally off topic from the feature request: You might want to include the 1060 in your list of graphics cards if you are willing to include the 970m (laptop version). The newer laptop 1060 is somewhere around 5 to 10% slower than the desktop variant, and the desktop variant is roughly equivalent to the old desktop 970. The 1060 should be a pretty good improvement over the 970m. It might end up saving you money as 1060 laptops start popping up to replace the 960m laptops.
