Thanks super fast delivery, I could install and test the card before the festival. The rise after one year from the GTX 780 OC was worth it. As usual software for OC regulation. Assassin's Creed: Unity short angetestet. Runs smoothly with the 'Owl' (Strix). The holidays are saved. I am running with: Intel Quad Core i7 4790K (also new) Corsair Vengeance RAM (PC1600, 16GB) ASUS Z87-V mainboard.
