Recently upgraded to a GTX 1080Ti and no longer have a need for these cards. Ran them in 3 way SLI for a couple years until I started getting some blue flashing on my screen (see video below). After doing some testing, it seems my primary card doesnt want to work well for SLI but runs without any problem by it self. The other 2 cards run just fine alone or in SLI. They currently have EK water blocks and back plates on them that I would prefer to sell them with but they will also come with their air coolers. Please feel free to ask any questions.
