Sapphire HD 6670 Low Profile Review @ OCC
 

The Sapphire HD 6670 provided a decent entry level gaming experience, while also being able to handle all office and media usage effortlessly. As long as maximum quality settings aren't desired, then this card will game just fine. Operating noise was surprisingly low and the temperatures were great! Overclocking was consistent with full-sized 6670s, with a gain of about 8% core and 15% memory. The packaging was perfect and included all the main peripherals needed.
