Need advice on getting a Gaming Laptop.

[Pyro as Bill]

Firstly, don't get an Alienware. I've yet to see an Alienware with specs that couldn't be done at half the price.

Secondly, the money you spend on a laptop could buy a much better desktop PC.

Thirdly, you don't really need to pay much attention to RAM or processor. If it's got a good video/graphics card the other parts should be fine.

Here's a list of laptop cards from best to worst:

My 'gaming' laptop has a Nvidia 8600M GT and it can play Bioshock, CoD 4 and anything from Valve. Today it's 102nd on the list. The games you plan on playing determines how far up that list you need to be. SLI and X2 means it has 2 graphics cards inside.

Quick look at newegg for laptops under $1000 has one with a Nvidia GTX 260M (20th best setup). 3 with a ATI 5650 (40th) and 3 with a ATI 4650 (50th). Depends what games you'll be playing and on what settings.
