8400M GT or 8600M GS?

[bumblebee_tuna]

What would you guys go with for a laptop? a 8400M GT or a 8600M GS? Of course the 8600M GS is a better buy but it's the difference between getting the 8400M GT with a 15 in. screen or getting a 8600M GS with a monstrous 17 in. screen.........

I would definitely go for the better graphics card as its not very easy to upgrade the graphics for a laptop.
