Received my other card today, so far so good, and what an enormous upgrade from the 470 SLI.
The thing I really disliked about my 470's was the noise, man were those loud under load.
Compared to those, the 670's are whisper quiet.
Shame that EVGA sent out a bad batch of cards, I've used their cards a lot and have had tremendous luck with them.
Hopefully mine hang in there.
Just checked Newegg, they only have the Galaxy card in stock now, these 6xx cards sure don't last long before selling out.
