To undervolt? To overclock

[Cavallino]

Folks, Ive read a few articles about undervolting...
Am I right in saying the advantage of undervolting is basically achieving lower power usage?
And consequently allowing the GPU to boost by itself to a higher clock?

What is the rule of thumb about undervolting?

Can an undervolt be used + an overclock?

Cheers, would you mind showing the voltage graph you used to undervolt?
Whats GPU boost?

Cheers bud, will do , how do you get MSI to show your GPU voltage there? It doesnt appear on mine for some reason

Cheers, will check this out.

Incidentally I am not sure why when I alter the GPU/voltage graph, and click apply I dont get a straight like, it still steps up a little towards the higher voltages....
