As our friends as 3Dprofessor announced FireGL 7600, ATI's new horse for workstation 3Dmarket has the support for two cards simultaneously.
This is something that we waited for
quite some time and now the driver is there to let you accelerate
four 3D accelerated displays with independent settings for
resolution, refresh rate, rotation and colour depth.
You can

but this will come in the next revision of drivers.
ATI really made a big come back in FireGL market and it looks that ATI's mainstream card can beat Nvidia's high end in workstation market.
