Laptops with two graphics processors running in tandem have been around for a while, but they're not usually the type you can actually use on your lap—unless you like getting third-degree burns, that is. A pair of new Toshiba gaming notebooks might break the mold somewhat, though. Nvidia boasts that the Toshiba Qosmio X305-Q708 and X305-Q706 feature three of its latest graphics processors.
In this case, the extra GPU should help keep power dissipation in check rather than make matters worse. Two of the GPUs are high-end GeForce 9800M GTS models, but Toshiba has also used Nvidia's GeForce 9400M integrated graphics chipset (the same one that debuted in Apple's new MacBooks). Thanks to the magic of Hybrid SLI, Toshiba's new notebook can power down its discrete GPUs and rely on a less power-hungry integrated graphics module to do all the video work. Nvidia calls this a "quiet operation mode," so we assume it dials down heat output, as well.
The Qosmio X305-Q706 starts at $1,999 with a 17" display, 45nm Core 2 Duo processor, 4GB of RAM, and a 320GB hard drive. For an extra two grand, you can get the Qosmio X305-Q708, which comes with a Core 2 Extreme, a 128GB solid-state drive and a 320GB mechanical hard drive, and quad Harman Kardon speakers with a subwoofer. Both systems weigh in at just over nine pounds.
