Asus just announced their ROG Chimera. A 17.3" gaming laptop with a 144Hz Full HD display and G-Sync. We're not sure yet, but we think this might be an IPS panel due a 7ms reponse time.

Asus -- Chimera is the world’s first gaming laptop with an ultra-responsive 144Hz wide-view display and a 7ms gray-to-gray response time, delivering smooth and seamless visuals never seen before on a laptop. 

Powered by the factory-overclocked Intel Core i7-7820HK processor that reaches speeds of up to 4.3GHz out of the box, it enables gamers to play AAA games at maxed-out settings. Together with NVIDIA GeForce GTX 1080 graphics — that can reach a maximum boost clock of up to 1974MHz — and Windows 10, Chimera is a bit of a powerhouse. Chimera brings together the best of laptop and console gaming: with built-in Xbox Wireless, gamers can effortlessly connect their favorite Xboxaccessories to the PC without the need for multiple adapters, and without having to swap controllers when switching between console and PC.

“Gamers have different needs, and this is what Join the Republic is all about: offering the best solution to every gamer, regardless of their gaming preferences,” said Global Marketing Director of Republic of Gamers, Derek Yu. “We’re all very excited to bring this incredible lineup of ROG gaming gear to IFA this year.”
