I have 2 evga gtx 680 4gb ftw cards running in sli.
they are running in my system in my sig.
I have been trying to overclock them , with not really any success.
They are on water cooling . and run about 44 c under load on an over clock of only +600mhz to the memory clock , and nothing to the gpu memory. power target is at 131% .
 
i have been reading people flashing bios to achieve better voltage and gpu clocks , but is it worth it, or much better in games than what i already have ?
 
also can someone go a little more in depth on how to flash bios, better over clocking methods  maybe a link that this has been discussed about this card in particular  ?
 
sorry for the newb  stuff questions , but ive read about alot better overclocks than I am getting and I want to achieve that if possible
