Here is the gold standard in mobile workstations. The ZBook series from HP brings uncompromised performance and great build quality.
The Fury 17 G7 is a big boy coming with 17.3-inch screens, which do come with good color coverage and accuracy, high TDP processors, and professional NVIDIA graphics. So far, we have some pretty standard stuff. However, the Fury has some crazy upgrade options, including four RAM slots, which is just insane.
