The i7 QM being a quad-core mobile cpu will be extremely power hungry so you wont be able to venture far from a power socket. Depends on your requirements.
There isn't really gonna be much within your £1,000-£1,300 budget. Possible the HP Envy 15-1110ea (Generation 2) which has been discontinued in the UK for some weird reason (you can only order the generation 1 model which doesnt have 1090p screen).
Sadly in the UK we are a little limited when it comes to high spec laptop's. For some reason everyone just wants sh*tty cheap things.
Alienware 15x?
MSI GT660? (not released yet and MSI laptops are difficult to get hold of anyway)
