A factory overclocked 5870 under £300 seems like a bargain to me. If you vote cold please explain why.
Equipped with a 92mm cooling fan and 4 pure core heat pipes, the PCS cooling system can easily dissipate heat from cooper base at a lower fan speed, efficiently cooling down the temperature by up to 15°C, when compared to reference board designs and in a low-noise setting, under 30dB. The PCS++ HD5870 features the ultimate factory overclocked setting, with core speeds clocked at 950MHz and memory speed at 1200MHz, ensuring gaming performance can go far beyond the standard version. Furthermore, PCS++ HD5870 takes advantage of our power efficiency design, consuming less than 250 watts, even under load.
