Maybe a stupid question, but I'm curious. Is there a reason you're going with a laptop over a desktop if you're indeed purchasing it for gaming? I ask because desktops are generally easier to upgrade later and usually cheaper for better parts. But if you travel a lot or something, then it makes perfect sense to want a laptop over a desktop. That way you can continue to hang with us from wherever you happen to be!
As far as the link goes, I'm not entirely sure what you've chosen parts-wise because it just selected "Standard" for everything. Aside from the RAM & Wifi card, were there any other particulars you were choosing on their list?
