I've been using the older Precision X just for temp/fan monitoring.  Decided the other day to try out the "OC scanner" button but it made zero sense.  I thought it was supposed to provide a way to automatically scan and find a stable OC for the card, but all it did was change to a panel where I was supposed to click on some lines in a voltage chart first.  Uh what?  There's nothing auto about that.  Some screenshots I've see of PX1 look like it actually does have an auto ability though so maybe I should switch to that now that it has some GTX series support?  I've never OC'd a GPU before so I don't know any of the specifics on how it works which is why I was thinking OC scanner would be nice to automatically find something that worked and if I didn't like temps just revert back.
