OCC has published a review on the PowerColor Radeon HD 5870 PCS+
In all of the benchmark testing, the PowerColor HD 5870 PCS+ did great! Usually in the top two, it got first place many times as well thanks to the factory overclock. The massive quad heat-piped heat sink also kept the core and card running cool under load even when overclocked. The graphics card easily clocked to 950 MHz core and 1320 MHz memory. After that, 100% stability was not possible, although in some games I was able to play for hours up with the settings at 1000 MHz on the core and 1400 MHz memory - a small voltage bump and this card could reach high frequencies!PowerColor Radeon HD 5870 PCS+ Review
