Computer Gaming Notebook Building?

I am currently looking to buy a gaming notebook. Now i've been looking everywhere. I have gone through Alienware, Gateway, other major companies. All outrageously over priced. Like Woah.
A few nights ago I found a site called iBuyPower.com
Here are the Specs for my $1500 computer (With next day creation and delivery. That means it will be at my house in less than 3 days.)

(Look below for more details)

So thats what I have. Then I found this great computer at BestBuy, but it only has a 1.8GHz.
The one I am looking at has 2x 2.5GHz/6MB Cache/800FSB

Someone want to tell me what is the better deal?

For gaming better to get a desktop, laptops aren't the best for gaming.

I probably wouldn't buy from that website, never heard of it and remember you get what you pay for. So many websites pop up everyday and are gone the next, do research before giving them that much money.
