3d Laptop

I am interested in getting a new laptop to work on my 3d with. My current one is just running an i3 chipset with a intel 3000 graphics.

So far I think I am getting a Inspiron 17r SE with the i7 chipset and the Nvidia GT 650M graphics.

My budget is about 900 to 1000.

Any suggestions or advice on getting a good laptop that will be able to handle sculpting up to about 1 M polys.
