The posters represent five custom series from Galax lineup, including Hall of Fame, Master, Boomstar (looks like new series, but they already have DDR4 Boomstar memory), Metal Master (these would be “the blue cards” we covered few times in the past) and Gamer.NVIDIA will reveal its new cards on September 1st. It's believed that custom-design cards will be available at launch, which will reportedly take place about a week after the paper launch announcement.
The text from the posters says: “One card with thousand faces, different from others”, “Your imagination, free construction”, “Firepower is power”, “Horizon World”, “Iron Armored Veyron, Hardcore Protector”. This is, as you might have guessed, a machine translation.
Furthermore, Gainward is running a contest that gives away discounts to (Chinese) customers that correctly guess the price and weight of next-gen Gainward cards.
