You all are overdoing it, guys. Bionic, first of all, I am not too keen on listening to people essentially saying "Wow you guys are so lame for not having the state of the art apsolute best laptops". I had a friend who does that. Purchasing like, new graphics card every week. I always hated his ranting on my "old" hardware.
Second, if you're looking for a gaming laptop, you'd damn better have a good reason for it. For the same amount of money you're buying that laptop for, you can assemble a PC so powerful that'll dim the lights in your house when you crank up the most hardware demanding games and proceed to play them at 60 FPS at all times.
I have a Lenovo 3000 N500 (59G) model. I need it since I'm living in a dorm, and moving home for weekends, I have continuos work to do for college. I purchased it 2 and something years ago, and it's still a beast.
If you ask me, the apsolutely most important feature in a laptop is the ability to access the main airway on cooling heatpipe. Mine takes two screws removed, and you're free to clean out everything from the airway.
This dude at the dorm wanted to clean out his Toshiba. We removed aproximately 20 screws and disassembled the lappy almost TOTALLY to finally access it.
You don't want a gaming laptop, you want a gaming PC.
If you want laptop, it's not inner components you should consider, but overall quality and ability for it to maintain "portable" which is what laptops are for, not weighting like a damned refrigirator with all them gaming components inside.
And oh yeah. My laptop is still pefrectly capable of playing COD4 and COD6, I just played some Far Cry on it, and I enjoy Left 4 Dead (1 and 2) in LAN with buddies.
Just a heads up on my two cents before you throw rather enormus large sum of money on something that'll later make you wonder "Hmm, what if I bought a PC..."
