PowerColor HD 7850 PCS+ 2 GB @ techPowerUp
 

PowerColor's HD 7850 PCS+ is the highest clocked HD 7850 card you can buy at this time. Thanks to its GPU clock speed of 1 GHz it provides excellent performance and the PCS+ cooler keeps everything cool and quiet. With just $20 over the AMD reference design, the price increase is also reasonable.
