I recently purchased an Asus DCUII 780 and it seems to be doing very well but I was wondering how to get a stable over clock with GPU tweak the card is currently at 941Mhz, I have sufficient airflow were cool sir is blowing directly on to the card and plenty of other case fans keeping things cool. i like to run my cards cool to increase the lifespan since I will not be upgrading anything soon but I would like to squeeze the most performance out of it while keeping at stable and cool. I am aiming for at temp lower of equal to 65-70c my temps at the moment are around 40-65c depending on how intense the game is. I am inexperienced at over-clocking but if anyone has any tips or would be willing to show me how it would be greatly appreciated,thank you!
