What a good laptop for Photoshop/painter/zbrush?

[gearh]

I'm looking to buy a new Laptop that can run CS5 dependably as well as
painter and zbrush. I'm thinking about the HP Elitebook 8740w but I don't want to be too hasty in this decision.

Any suggestions?

Use a desktop if you want to do serious work. The cost of a laptop to do this is an unnecessary expense in my opinion.
