Which laptop is better and how are the prices different?

That AlienWare is not worth it if you're only getting that much RAM, I mean with such a price difference the parts should be more upgraded, better, I mean 1GB of RAM? Increasing the price for LOWER amount of ram?! You should have at least 2 GB if you like gaming, the 2 laptops are very similar but for the price difference the AlienWare isn't worth the extra cost! The main thing for gaming is the graphics card and with the extra money try to find something with a better graphics card than the Dell. If you were to select 1 of these I'd say the Dell from the specs. They're just too similar and the AlienWare with so much more money doesn't really outperforms the cheaper one and it has LESS RAM, plus the Alienware also has less harddrive space. For the extra price everything should be much better and faster!
