Most of the issues that people had with the Asus 670's were related to them using the GPU tuning software included with the card. Asus acknowledged that was causing the "Overboost" on the cards which caused them to crash. I picked up my 670 Top version and downloaded drivers from Nvidia and used MSI afterburner. Only crash I had was when I tried undervolting my CPU overclock to lower temps. Cheers.
