I had a D*ll Insp*ron 15R which was just sub £600 and quite powerful.

Spec:

i5 430M CPU @ 2.27GHz with Turbo Speed to 2.53GHz
4GB DDR3 RAM
500GB HD
ATI 1GB GDDR3 5470 Dedicated Gfx card
15.4" LED Lit LCD Screen 1366x768 Reso (720p)
VGA & HDMI slot
DVDRW
Win7 64Bit OS

Could get quite loud in Gaming (but then wot laptop doesnt?) However, was quiet when just surfing/office work.
