Laptop

[Pickers]

After having had it with my desktop, and downsizing to a flat, I am looking for a new laptop...
Heres what I have found:

Dell Studio 15
Intel® Core™ i7-720QM Mobile Processor (1.6GHz, turbo up to 2.8GHz, 6MB L3 Cache
Genuine Windows® 7 Professional, 64bit, English
15.6in Widescreen Full High Definition (1920 x 1080) WLED with TrueLife
4096MB 1333MHz Dual Channel DDR3 SDRAM [2x2048]
320GB (7,200rpm) Serial ATA Hard Drive
512MB ATI Mobility Radeon HP 4570

£768
£710 after discounts and quidco.

Am I going overboard with this?? I dont really do an awful lot of gaming, but feel I want the power of a desktop just in case...
I could go smaller I spose. Dunno if this is a deal not to miss :/


Edit: If I downgrade the display from full HD, It drops to £680...
