VS

Asus ROG Gaming G750JM

Intel® Core™ i7-4710HQ
display - 17 inch FHD (1920x1080)
12GB ram
750GB HDD
NVIDIA® GeForce® GTX 860M 2GB graphics

i think the lenovo has the kepler version of the gpu and asus has the Maxwell

Added (1). BOTH ARE £999

Definitely Lenovo. It has more ram and a hybrid disk (both SSD 8GB and HDD, the rest). 8GB SSD is really not much, so I'm not sure it makes that much of a difference. If you know the OS alone is around 15GB these days… It also has better speakers.
Otherwise, the specs are pretty similar besides the size of the screen. The question is, do you really want a 15" or a 17" screen? You can later always upgrade to more ram (you're most likely not going to use more than 12GB) and you can always upgrade your disk as well. The screen is one of the things you can't upgrade on a laptop.
I would most likely go for the 17" screen and upgrade later on when the money comes in.

Easily the lenovo.
