Expreview has done some tests on the new Powercolor product, the Radeon HD 4870:

One of these tests is FurMark and the HD 4870 fails to complete one minute of FurMark’s stability test. Failure symptoms are VPU recovery message, red LED (on the PCB) that shines…

For one thing, BIOS limited fan speed too low, that results in a higher GPU temperature; For the other thing, it gets through 3DMark Vantage, but fails to complete FurMark test. We believe it’s the BIOS setting that causes these problems and asked PowerColor for a new BIOS, but the answer was not available yet.
