we would ask about the entire device.
What do you want with a laptop do?
The latter display has a Full HD resolution. (Due to play a mobile graphics unsuitable, however, ideal for movies)

So 2x2.5 with 6 mb cache

4gb RAM

ati 4870

it is from Alienware

I use it for games

You have the resolution to Full HD almost always down, so would offer the better display.

I hope you make the noisy fan of the notebook from nothing.
