can you post a screenshot of the water?
check in the advanced controls, most games have a screenshot capture on print screen or F10 or something like that
IMO, OCing a vid card is poinless.
usually you will gain 1-2 fps, which you wont even notice while playing, not to mention the extra heat and decreased lifespan
the only reason I got a factory OCed vid card was cus they orderd me the wrong card but still charged me for the non OCed one
