Get a dell m1710, it offers almst 3 hours of battery life, and 2nd highest frame rates, 1st for 17 inch laptops. XPS service is alright, not great, but its a good buy for 3.5k. Going for a 19 inch+? Get voodoo envy u909. Need a portable gaming unit? Thinkpad t60 or falcon fragbook. I own all of them, never buy a dell except m1710, and m90. Never buy alienware, period. They have sucked ever since dell bought them. Also, dual graphics cards dont improve frame rates at all. RAID doesnt either. Those are only good for desktops. Get 1 HD, 1 G card, andan extra battery :P
