Gigabyte has just announced the GeForce GTX 980 WaterForce Tri-SLI (GV-N980X3WA-4GB). This is probably the most powerful graphics card set to ever come out of a single box. This monstrosity is made up of three GeForce GTX 980 graphics cards, with a factory-fitted liquid cooling loop that sits outside of your case.
Each graphics card features a factory-overclock of 1228 MHz core, 1329 MHz boost and 7.0 GHz (effective memory). Each card also has a liquid-cooling pump block over the GPU and a base-plate that conveys heat from the memory and VRM to that block using heatpipes.
Coolant tubes from each of the three cards run to the external unit that has an independent 120 x 120 mm radiator for each of the three cards. The fan speeds and coolant pressure of each of the three loops can be controlled at the units front panel that has an LCD display that shows the information. Also as part of the kit you get a custom 3-way SLI bridge, a reinforcement bream to counteract PCB bending, a 5.25-inch front panel bezel to run the coolant tubes out of your case and some tubing management grommets.
Gigabyte did not announce any pricing or availability, but expend this unit to be quite expensive!
