So, my P370EM is configured with the i7-3630QM, 16gb RAM, and two 7970Ms. I've also got a 256gb Samsung 830 and a 250gb Samsung 840 in it, although with a Crucial M4 256gb in the mSATA and 1TB hard disk. I'm using the Intel 6235 wireless card and the laptop runs Windows 8.
The machine is fast, faster than any other laptop I've ever seen or used, it scores higher in 3D Mark 11 than my PC (although this makes me trust 3D Mark less). The computer is bulky, and not light, and the battery life is nothing special.. but that's the trade off for a laptop this speed.
A few minor annoyances:
1. The laptop does have a full-ish keyboard with a number pad, it's also backlit (and you have three multicolour regions that you can change the lighting on), however, it doesn't have dedicated Home and End buttons, instead, Home and End is overlaid on Pg Up and Pg Down, making you use the function key to use Home/End, and making the Shift+Home/End more difficult that it has to be.
2. The touchpad doesn't have any obvious buttons and the whole pad presses down... this pad was designed to be used where one finger click means left click and two finger click means right click. You can configure this to have the traditional bottom left is left click and bottom right is right click... however, it doesn't really feel exactly the same as the whole pad will click down if you apply pressure to it.
