You no longer need a huge, water-cooled rig to play the latest blockbuster shooters, with plenty of gaming laptops doing a fine job of marrying performance with portability. But a divide still exists, with even the best mobile GPUs defined as "desktop-class," which is a nice way of saying they aren't quite as powerful as the cards made for home office-hogging towers. That said, in what NVIDIA claims is an industry first, the company has today announced its top-end GeForce GTX 980 desktop GPU is headed to laptops. Not to be confused with the GTX 980M -- NVIDIA's previous flagship GPU for notebooks -- the GTX 980 for laptops is exactly the same as the desktop version, offering identical gaming performance.
