GT780 Takes Notebook Gaming Full-Force
The GT780 steps up the gaming experience from its midsized counterpart with a 17.3" screen. Spec’d with a mythical GeForce GTX 500M-series card, we hope the actual model installed will end up being the flagship GeForce GTX 485M. Improved speakers and RAID capability are carried up from the 15.6" GT680.
Nvidia is dedicating the near-term 500Ms as GT models, which means these will all be mainstream parts with less 3D prowess than the previous GTX 460M. In other words, don't let the naming confuse you; 400M-series parts are still fastest.
