My other half has a slightly earlier model, hers has the GTX980 in it and 32GB RAM but I think most of the spec after that is the same or very close to it. She got it from Overclockers and it was also about £2,000 which is an eye watering amount of money to be sure but for her it is her main rig, we do not have the space for a 2nd desktop so she has a laptop...
To say that the laptop is a beast is, to be frank, an understatement! She finally managed to run Batmam Arkham Knight balls to wall maxed out and the machine didn't even breathe hard!
Imho it is a lot of money but boy you get a whole hell of a lot of machine for it!
