Almost all of them have the same screen resolution so how to differentiate on that? Yes, you find a few folk hunting tor the now elusive 1080p displays, backlit keyboards but you have a price point.

Try the list at http://www.amazon.com/Best-Selling-Gaming-Laptops-2011/lm/R30ZVRZ01W4P4E then see what models match your price and more.

Again, these are shorter lived units dues to packing all that into a laptop. But you are buying this knowing that going in.
