The update is finally here! I have been waiting to buy myself a laptop for college and I'm finally ready to hit the buy button. With these new lower prices I have decided on a 15" MBP!! My question is should I go for the 2.53ghz or 2.66ghz configuration? Not really for the processor but for the video card? Is the 9400 noticeably slower? Is the 9600 that much better? How are these new mobile chips apple now seems to love throwing in just about all their machines haha. Thank you very much for any input!
