Thanks for your question!

There are actually a couple of good threads that are already going on the forums here.  Check out this one or this one for good direction from many experienced users on the forums.

Also, you could sign up to the forums and tell us what type of games you are looking at playing.  That will definitely help us tailor some advice specifically to you and your needs so that you can get exactly what you want

Keep in mind as well that with laptops, you will end up paying more than if you were getting a desktop with similar specs.  Also, desktops, especially for higher performance stuff, tend to run better than laptops with equivalent specs.

Good luck!
