How are you getting along with your new purchase Spike?
I've got one of these coming, similar spec as yours but only a 1060 GTX and the normal 1080p screen. Does have the 256GB SSD and 1TB drive. Seemed ok for £1500.
I was going to buy the older R2 version for £1249, but it's thicker and apparently gets quite hot.

That's not a bad price there though I probably would've stretched a teeny bit more for the 1070 and the QHD screen.
The new alienware laptops have a huge design flaw - the heatsink is triangular instead of square resulting in uneven core temps. Certain cores can be 10-20 degrees hotter than the others resulting in early throttling and thermal shutdowns while gaming. I cancelled my order and many people are returning/refunding theirs. Reddit and various google-able notebook forums have more info. I recommend you check your core temps before the 30 day return period ends.
I've read that undervolting the cpu cures the issue. Not something you should have to do, but I don't really fancy any of the other laptops out there for the same money. Asus and MSI all seem to have issues of some kind.
