Each card is different...

Try testing it in Heaven/3D Mark Vantage/Games. If you see artifacts, raise your voltage.

tah question is, what risk are you taking to achieve what boost ( and how expensive/fast is the gpu you intend to do it with ) i guess you will get an increase of about 15% which is not worth it to me regarding that you have two 580s under your pillow..
i dont want you to tell what to do but i think its just too early to OC that for 24/7 or is it for benching?!

You'll probably need somewhere between 1075 and 1200mV. As mentioned, every card is different.

What voltage did your card come at 'stock' (commonly referred to as 'stock VID')?
