I was in the market for a top end laptop a month ago with a budget of £1700 (a little over yours I know) for music production and graphic design on the move. The only laptops that caught my eye were 2 customisable Clevo barebones laptop kits, that are sold through specialist retailers:
The first and my prefered is based on the Clevo D901C. Its based on desktop technology and can use Intel quad core desktop processors such as the Q9550, DDR2 ram and has space for 3 HD's. Its a helluva laptop and uses the 9800M GT (or GTX, but try and get the GT as performance difference is tiny compared to the extra cost) I managed to find one for £1700 with 2 x 200gb HD's in raid 0, 4GB ram and a Q9550. Only thing is it's a hefty thing and dont bother trying to use the battery

If you win the lotto, you can even stick 2x 9800M GTX cards in there in SLI!
The second is cheaper at around £1500 and is based on another Clevo barebones kit the M570ETU. This one uses mobile processors, anything up to the new mobile quad core QX9300's but will only be the dual core T9400 2.53ghz for your price range, DDR3 ram and only one Hard Drive. Once again it uses the 9800M GT series cards. This one can actualy be used away from a power source
Both come with 1920x1200 glossy (ew) screens, subwoofer and some kinda surround sound speakers built in and all the bells n whistles.
Now a couple of things to remember; The only way to get these offerings in the UK is through some kind of gaming/PC building specialist company who come up with their own fancy branded names for the laptops. Prices have also gone up in the past month due to the crappy exchange rate so don't quote me. Also, unless you're spending £2300+ on a laptop with 2x9800M GTX's in, don't expect to be playing crysis on any high settings. Saying that I've seen Far Cry 2 on the M570ETU system looking good and playable.
As for what I decided? Well I'm about 70/30 in favour of just building an i7 rig and buying a mid end laptop as well instead of going all out on a laptop. But the choice is yours. I would say if you're thinking of gaming, just build a desktop. If like me you could do with being able to take your work around with you, then the choice is a bit harder
Hope this helps
