1st notebook build...

Here's a very important tip about gaming notebooks: get the best CPU and GPU that are available because games are improving so fast that your notebook will be outdated much sooner than you expect. I bought a notebook 1 yr and 10 months ago and had the best CPU and GPU available put in it. Last week I bought Mass Effect, and my notebook won't play it at all. I bought Assassin's Creed, and I have to play it on the very lowest settings, which is dissapointing. 
   Right now the best available CPU for notebooks is the Intel Core 2 Extreme X9000, and the best notebook GPU is nVidia 8800 GTX. I recommend that you get those, and don't be surprised if they're outdated in less than 2 years.
     Also, be aware that the GPU put into notebooks is different (not as good) than the one put in desktops, even though they have the same number. In other words, the 8800 GTX made for laptops isn't as good as the 8800 GTX made for desktops. So, if you're looking to buy a game and under Requirements it says that an 8800 GTX is OK, the game may not play on your notebook, but it will play on a desktop. This is because of the lesser amount of space inside a notebook, so the manufacturer has to make the GPU slightly different so it will fit inside.

 Once I get the B. Franklins together, this will be the system I would like as my first laptop build:
