Probably nothing. But why does it have to be justified?

Extra 2fps for DX use.

I tend to buy my cameras with the grip already built in. But I do have grips on my D200, D7000, and Canon T2i.

I'd rather pony up the money for a grip, since I could count on 1 hand the number of times I've used a speedlight. And since I have to place remote cameras in spots I may not be able to get to during a shoot.
$450 is a lot of money. But the choice is yours. Buy it, or don't. Only you can decide that. I'm buying it and not worrying about it. Buying the D800 means I don't have to buy a 400/2.8. So that puts me about $9550 to the good. Your economics scenario may be different.
