SLI laptops are a dime a dozen these days, but Alienware's Aurora m9700 is one of the few 17-inch SLI lappies around, and it just got a severe performance boost in the form of dual nVIDIA GeForce Go 7900 GS graphics cards with 512MB of memory apiece. In celebration of the new juicy spec, Alienware is throwing down two new colors: Conspiracy Blue and Cyborg Green, for $100 extra. It doesn't look like many other specs have budged, the processors still top out at a 2.4GHz AMD Turion 64 processor, and there are options for MIMO networking and a TV tuner, along with the standard Bluetooth and gigabit Ethernet. Prices start at $1700, and the dual 512MB graphics will bump that price up to $2300. Everything should be shipping by the 11th.
