I can't recommend these any more highly
www.pcspecialist.co.uk/laptop-computers/ you can configure the parts you want yourself and there's plenty of options. I have the Enigma but I chose the higher end parts plus a 2nd hard drive so it was £700 ish, their CS is second to none too. If you need any help configuring just ask.
Have a look at these specs I put together thinking of your budget and requirements.
