Best gaming laptop for $1000 and with a 15.6" screen or smaller

Welll... the question pretty much resumes it all, just asking for a gaming laptop in the $1000 mark that's not too heavy nor too big. I almost bought a 16" one but found it to big to consider it a "portable" piece of equipment you know  

1_What is your budget?

$1000 Max

2_What is the size of the notebook that you are considering?

14"-15.6" not too heavy, not too big.

3_What screen resolution do you want?

I really don't care about that...

4_Do you need a portable or desktop replacement laptop?

Preferably the most portable it can get. I know great preformancers are a little on the heavy weight side, so just not too heavy I think.

5_How much battery life do you need?

Doesn't matter... more that 1 hr I think...

6_Do you want to play games with your laptop? If so then please list the games that you want to with the settings that you want for these games. (Low,Medium or High)?

Of course!
Thinking of:

Mass Effect 1 & 2 med-high
Crysis med-high
Orange Box high
Fallout 3 high
The Witcher high
Company of heroes high
Empire Total War med-high
etc etc

7_What other tasks do you want to do with your laptop? (Photo / Video editing,watching movies, Etc.)

Dunno... programming, visual desing, web design, basic office tasks, etc.

8_How much storage (H.D.D Capacity) do you need?

Dunno 250GB+ I think, If it is posible a 7200 rpm drive.

9_If you are considering specific sites to buy from, please post the links to them.

Preferably stores (Bestbuy, Office Depot, Walmart or local Retaliers on the San Diego area)

10_How long do you want to keep your laptop?

More than 2 years, even if it's posible maybe 4 years. I know that laptops are the most faulty electronic devices out there but if it's not too much to ask, I would like a long term buy. I don't want to replace it in less than 2 yrs.


11_What kind of Optical drive do you need? DVD ROM/Writer,Bluray ROM/Writer,Etc ?

Whatever

12_Please tell us about the brands that you prefer to buy from them and the brands that you don't like and explain the reasons.

I like Asus, Toshiba, Sony and MSI. Cool designs, classy, great builds, very reliable and good performance.

I don't like HP and Gateway, too faulty.

13_What country do you live in?

México, but I have a Visa and live near the border so...
