Summary: Runs very hot. Had some stability issues before I figured that out. Runs about as fast as a GTX 570. I like the non-reference fans although they get loud at 80-100%. Very long cards at 12" so they can only go into full towers and some mid-tower cases. I bought this to complete my Bulldozer Scorpius build, plus I liked the look of the product. Plus has advanced features for voltage monitoring for further overclocking over its already 40Mhz gain over stock.
