PowerColor's SCS3 HD6850 is the first passively-cooled Radeon HD 6850 card on the market, and it's the fastest board we've seen without a fan (not counting water-cooled solutions, of course).
Its specifications sacrifice nothing you'd expect from a reference Radeon HD 6850 design, and that includes graphics processor and memory frequencies. Perhaps the card's most significant drawback is that it requires three expansion slots, potentially limiting the environments where it'd work well (certainly not in small form-factor installations). The card's price really isn't a surprise, though. You pay a roughly $35 premium for the massive passive cooler compared to PowerColor's actively-cooled Radeon HD 6850.

PowerColor's retail package includes the card itself, a driver CD, a manual, a CrossFire bridge, a DVI-to-analog VGA adapter, and a DiRT 3 coupon.
The card features two DVI connectors (only one of which is of the dual-link variety). In addition, there is one HDMI output and one DisplayPort connector, both of which are full-size. This is the standard, albeit still excellent, connectivity package compared to Nvidia's best efforts in the mid-range field.
