I have the evga gtx 580 black ops edition.. And when i do some googling, it is factory overclocked but there is a higher version of it which is the gtx 580 waterblock edition by evga and the speed is faster.. Im using the black ops edition and using waterblock to cool it.. Should i increase the card speed same as the evga gtx 580 wc edition? Will it be stable? My graphics card temp is 25-28 degree on idle...
