2 980m GPUs in SLI and only a FHD panel?! I sure hope there is an upgrade option to justify that graphics horsepower.
You do realise that the GTX 980m has nothing to do with the desktop version of the GTX 980 right?
Performance-wise, the 980 mobile is someware around the GTX 780 (non-ti version), witch makes it good for playing most games at 1920x1080 + high to ultra details depending on the game. While two GTX 980s for the desktop could drve most games at 4k, two GTX 980m s will not be able to do so.
The 980m has 1536 cuda cores, while the GTX 970 (desktop) has 1664, and the GTX 980 (desktop) has 2048 - witch puts the GTX 980m in between the GTX 780 and the GTX 970 - performance whise.
Please don't be fooled by the names of mobile GPUs. For example the R9m 290x is basicly a HD 7870 - it has nothing in common with the desktop version of the 290 witch is about 3 times faster.
Also, please STOP REQUESTING ludicrous resolutions on laptops. Scaling down the resolution makes the image quality blurry and pixelated. Also, 30fps is not an acceptable framerate for gaming. I'd rather game on 1080p @ 60-80fps then on 4k at 30fps.
