When pictures of the PowerColor Radeon HD 4870 PCS (Professional Cooling System) first hit the internet, it caught the attention of many for having a very upscale hardware feature set. It comes with a 6-phase power circuit, it is based on the SuperRV770 design methodology, comes with a cooler made by ZeroTherm that looks promising. As expected the card comes with overclocked GPU and memory parameters.

Expreview decided to give one of these cards a go before they hit the markets. They spent a day extensively testing it and found a glitch with the BIOS with which the card's stability at those parameters is marred. The BIOS has a very low fan-speed limit (the maximum speed to which the fan can be adjusted by the user). This results in a very hot GPU and instability during prolonged operation. To give you an idea, the card was able to clear the 3DMark Vantage benchmark but simply gave up on them when running the FurMark benchmark, it failed to clear the tests. Nonetheless, this product gained a very positive opinion, hopefully with this glitch cleared by PowerColor, the card could prove to be promising.
