The PowerColor HD 6870 PCS+ is the first non reference HD 6870 I have looked at and it is equipped to deliver excellent performance right out of the box. This card is factory overclocked with clock speeds of 940MHz on the Barts core and 1100MHz on the GDDR5 memory so you get a boost in performance to start with. When it comes to overclocking higher, there is some headroom left on the HD 6870 PCS+, though not much. On the core overclocking I was able to push the card to a clock speed of 1003MHz (63MHz) and 1208MHz (108MHz) on the memory. This amounts to increases on the order of 6.5% on the core and just under 10% on the memory. These increases, although slim, still offer measurable gains in performance across the test suite. Since the launch of the 6800 series the overclocking headroom has been more substantial on the lower clocked HD 6850 than the upper tier HD 6870. Even so, with a little work you can gain additional performance for not much more than the cost of your time.
The HD 6800 series cards offer Eyefinity support with differing levels of support based on the cards' connectivity options. This card supports Eyefinity with up to four monitors using the default connectivity configuration that includes two Mini Display Port connections and single HDMI port and two DVI ports, one of which is Dual Link capable. Stereoscopic 3D is available through aftermarket suppliers and a middleware solution if you choose to go that route since AMD is all about "open" solutions versus proprietary hardware. One thing that came as s surprise while testing was that the power consumption at stock clock speeds was much lower than the reference card during the stock idle and load tests by substantial margins. The three heat pipe cooling solution delivered better temperatures during the idle and load tests at the default clock speed level. Under load, the difference was only two degrees lower than the reference solution but the main difference comes in the noise associated with the cooling solution when the fan speed ramps up. In this regard, the PowerColor HD 6870 PCS+ holds the edge. When you get down to its essence, the PowerColor HD 6870 PCS+ is faster than the reference cards, runs cooler and uses less energy, not to mention looks much better by comparison than the reference solution. With those kinds of attributes, plus the addition of one of the most popular games on the planet, you have a winning solution.
