yes i was aware it was being realesed today but could only find one review site,
im sure more will appear soon.
This card reports as a single unified piece of hardware in Windows, which is a better solution than virtually separating the two “twins”. Although it goes by the codename R680, we are dealing with two R670 chips, however, a marketing difference had to be made. Basically, all the characteristics of an ordinary HD 3870 are present, just multiplied by two. That means: 2x320 stream processors, 2x16 ROPs and so on. Just like the other HD 3xxx series models, this card has native support for DirectX 10.1, Shader Model 4.1 and OpenGL 2.0.

you can read more here,it also has a crysis benchmark
