Most first-tier graphics card manufacturers these days have liquid-cooled versions of their top-end cards. MSI, Gigabyte, and Asus all offer GTX 1080 cards with an AIO liquid cooler strapped around them. Gigabyte is now trying a different tack: a GTX 1080 that comes from the factory with a waterblock installed, ready to be slipped into existing liquid-cooling loops. Say hi to the "GeForce GTX 1080 Xtreme Gaming Waterforce WB 8G," not to be confused with its "WB"-less cousin.
The card comes out of the box neatly sandwiched between a metal back plate and a full-coverage copper waterblock with an acrylic window. That's not all, though?the card's RGB-LED lighting shines through the waterblock's window and sides. One has to wonder if it flashes bright red repeatedly in case of a coolant leak. The card's GPU can hit 1898MHz in the regular "Gaming" mode and 1936MHz in "OC" mode.
