We've seen the ASUS ROG Poseidon before, the last one that comes to mind being the GTX 980 Ti from Computex 2015.  The name refers to the hybrid cooling solution which incorporates both watercooling and aircooling, giving you the option to add watercooling to increase your thermal dissipation or to remain with aircooling.  [H]ard|OCP is working on a two part review of the card, this first article covering the performance of the card on aircooling alone.  The card exceeded the quoted boost clock of 1708MHz, averaging 1939MHz in the BF1 test on default Gaming Mode clocks, 2025MHz once they overclocked.  That is an impressive clock but there are other air cooled cards which are able to reach higher frequencies so it will be interesting to see what adding watercooling to the card will do.

"Air cooling? Liquid Cooling? How about both, the ASUS ROG Poseidon GeForce GTX 1080 Ti Platinum Edition hybrid video card can run them both. In Part 1 of our evaluation we will test the video card on "air cooling" and overclock it as high as possible. In Part 2, we pump liquid through its veins and compare overclocks."
