Suggestions for a gaming notebook under 1300 GBP

Hi guys, I'm seeking advice on what would be the best purchase in the UK if I want a laptop that is good for gaming and for 3D designing. The optimal price range I'm looking for caps at 1300 GBP but prefer those under possibly even pushing it down to 1000 GBP. A couple of things I'd like the laptop to have:

possibly a screen above 17"
at least 4 GB RAM if possible DDR3 if not DDR2, but with 800 Mhz.
very good video card as I will be playing games like Aion, Dragon Age and I want every graphic option capped at maximum.

So what's your suggestion at the moment I saw MSI GT729-253BK for 1279GBP, which I'm planning to buy but would be intrested if there is anything better around the same price range.

Cheers
