I'm getting 1350 on one and 1330 on the other. The first card could possibly go higher; I haven't tried yet.
The very first card (which I returned) could barely reach 1220Mhz.
I'm probably going to end up selling one of the cards as I don't really need all the horsepower. A single 670 is pretty good enough for me right now.
Just got mine in today. Looks like I can get 1292 MHz core and 1762 MHz memory with the fan on Auto. I get scores of over 3000 on FurMark and Heaven.
With fan boosted to ~ 70%, I can get 1310 MHz core.
By the way, does anyone know how MSIAfterburner starts up automatically in Windows when the little box is checked in the lower left corner of the main application window?
I don't see anything in services, startup items, or the registry???
