Sapphire Radeon HD 4670 Crossfire Review @ TweakTown
TweakTown released this review of Sapphire's variant of the ATI HD 4670 in Crossfire. It appears that in Crossfire it destroys the NVIDIA 9500 GT and keeps up with a single ATI HD 4850. For a mid-range Crossfire setup that comes in under $200 USD and is able to play current games at 1600x1200 with settings on medium to medium high, this would prove to be a one of the best "bang for the buck" setups currently available.
The Bottom Line: The performance of the HD 4670 was an absolute shock. No doubt NVIDIA are worried about this new card which could become the new king of the mid-range hill.
