Here’s one for the “traveling-executive-by-day/extreme-gamer-by-night” crowd. 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. Why not just go with the more powerful graphics card and burn through those spreadsheets? Xtreme figures there are times when you’d like to preserve your batteries, and running a less robust graphics engine is one way to do that. We’re not sure how much juice that actually saves, compared to other measures like 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.
