OK. This is a bit interesting, and I misinterpretted Clevo's model numbering scheme.
According to their website correctly, the "P775DM" will be the model for NVIDIA GeForce GTX 980M/970M (mobile GPUs). However, the P775DM1 (notice the trailing "1" - which is also the title for this thread), will be the model sporting the GeForce GTX 980 (Desktop GPU). So for those awaiting the appearance of this model on vendor websites using the Clevo numbering scheme, make sure you verify the correct model number / feature before ordering.
[ Not that you wouldn't do that in the first place. :>) ]
On a related note, here's one of the first reviews I've come across - http://www.notebookcheck.net/Schenker-XMG-U716-Clevo-P775DM1-Notebook-Review.155740.0.html
