Looking for the right good laptop to buy

So I have been looking at computers and laptops to buy witih about $1400-$1500 to spend, and when it comes to laptops I am unsure on the correct methods and precautions when choosing what to buy.

Now I am looking for a gaming laptop that can handle good loads and streaming games, for I am a league of legends player/streamer and now I am chosing to move on to other games, I plan on playing D3, guild wars 2, maybe even tera. I like to play good graphic single player rpgs like witcher 2, bioshock games and many more.

I am very interested in mobile play, I like to travel and have easy light access to a laptop, but If it is better by a tenfold I am considering building a desktop.

The current laptop i am looking at right now is the Asus G74SX - RH71

17.3-inch LED-backlit Full HD display for immersive cinematic experience with resolution up to 1920 x 1080
2nd generation Intel Core i7-2670QM processor with Intel Turbo Boost 2.0 Technology for the best visibly smart performance that adapts to your needs
NVIDIA GeForce GTX 560M graphics with 3GB GDDR5 VRAM for leading DirectX 11 gaming
ASUS Power4Gear Hybrid that innovatively saves battery life and delivers extreme performance
SuperSpeed USB 3.0 for quicker device charging and up to 10x faster transfers than USB 2.0
750GB 7200RPM hard drive and 12GB of DDR3 system memory for smooth computing and ample storage for all your games and media files
Backlit gaming keyboard with ergonomic tilt-up design for comfortable control in any lighting environment
EAX Advanced HD 5.0 Audio for premium gaming sound
cost = $1399

I dont know if this is the best I can get for my buck but it looked pretty appealing to me.

 

what's the warranty on that?

doesn't best buy sell that one for $100 cheaper ?

as far as gaming laptops, i haven't seen ones with gtx graphics cheaper than asus

 

If you are in not hurry to purchase you may want to look at this thread http://forum.notebookreview.com/sag...hread-pxxxem-series-p151em-p150em-p170em.html
The P170 (17 inch screen) will have lighted KB, and OPtimus for better battery life.
Depending on the Video Card, I am going for one of these.
