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