The Raptor 766X actually has two graphics engines: an Intel integrated graphics processor for number crunching and an nVIDIA 6600 G-Force Go for fragging. Xtreme figures running a less robust graphics engine instead of two high power ones, will help to preserve your batteries when you're not gaming. Not sure how much juice it actually saves, compared stepping down your CPU's clock speed, lowering your display's brightness (the display, after all, accounts for as much as a third of a laptop's power consumption) and spinning down your hard drive. But if it helps you justify writing this off as a business expense, more, er, power to you.
