Extreme Tech has done a complete review and comparison of the new Radeon HD 4870 X2 with NVIDIA high end GeForce GTX 280 card. The website concludes:

“So ATI’s new high end card based on the RV770 GPU – indeed, two of them – is finally here. True to the company’s (AMD) promise, it is clearly the performance leader of this generation. If you want the fastest graphics card money can buy, the Radeon HD 4870 X2 is it.”
