Why pay extra for a laptop? Yes, it will cost you probably 50% or more for the same specs as a desktop.
Get a desktop if you are serious about making games with FPSC X10, because you'll save money and it will run better. (Use your laptop for v1 games and XP.)

Sure it will run on an 8600GT, but not as good as the 8800. (you need an 8800 for it to run well and those are not in laptops!)
I have the 8500gt which should work too, but the 8400's and the 8300gs are probably going to fall short.
The 8400 and 8300 are not even SLI compatible so they are like bare spec X10 cards.
While they should run X10 technically, they probably won't run it well.
