Best sub-£1200 gaming laptop

Although I have a powerhouse desktop, I have started to travel more and my Early 2011 13' MBP is with my aunt, so I have a Core 2 Duo/320M MBP as my laptop, which can barely handle me typing, let alone games. Here are some requirements and the two laptops I am currently considering. Thanks!

Budget : £1,000-1,200
CPU : I5 or I7, preferably Ivy B.
GPU : AT least 5870M or 560M
SDD : Not required, but a 120GB or 240GB would be nice, depends on total price
HDD : No less than 500GB
OS/Software : Win 7 and Office Home and Student
Other : A 720p webcam would be nice, once again optional
Once again. thank you for your help, you guys also provided immense feedback on my desktop, which is great

Considering :
£1,030
