I have a PNY 660ti and picked up Evga Precision X after watching a review on it.

Does anyone have any expeirence with overclocking the pny 660 ti using this software?

and if so what settings do you recomend?

Couldn't be simpler, just increase the clock and memory clock as high as you can while keeping it cool enough and stable.  Try and get the memory clock as high as you can though.  The GPU is really good but it's strangled by the smaller than normal memory bus.

I was more interested in some actual numbers, rather than trial and error shooting in the dark, but that's okay

 

Is 78C to hot to keep it running at?
