so does this program really work on overclocking the graphics card and gives extra performance?
there are 2 options for overclocing
engine and memory so what number should i set it to? and do i need to do anything else ?
If you are talking about Asus smartdoctor then it is made for tweaking their cards. When you overclock you do it in small increments, gradually increasing until instability shows up then backing of a few notches.
