Depends on what type of games you are trying to play and if you are looking more for batter life. I am a big believer in getting something in your budget and then putting in a SSD drive. You'll notice more of a difference in that than with a quad core mobile processor unless you are trying to do heavy gaming, video, photo, and other process intensive things.
What are you looking to do with your new laptop? I know gaming... but what type and what other things?
