Alienware unveiled two new SLI-enabled gaming laptops today, one 19-incher with a slick color-shifting paint job, and another that may be the first 17-inch notebook on the market with two graphics cards. As far as features go, both machines sport almost identical specs to the other SLI models we've seen
: XP-powered AMD Turion 64 processor, two 256MB nVidia GeForce Go 7900 GTX cards, anywhere from 512MB to 2GB of RAM, WiFi (Bluetooth optional), 4-in-1 card reader, and your choice of hard and optical drives. Available for preorder immediately, the 19-inch mALX starts at $4,500 ($500 less than Voodoo's similar Envy u:909
) while the 17-inch m9700 (pictured after the break) goes for $2,000 and up.
