New Professional Video Cards from ATI

Following closely on NVIDIA's heals, ATI has announced it's latest line of professional video cards. There are not less than 7 cards which occupy this niche, with the top of the line aimed directly at its competitor.
However, NVIDIA is not sitting put, since they announced that the Quadro cards will support SLI, the ability to inter-connect 4 cards, in top of the line workstations.
If you are dreaming of one day being able to pair two cards on your Mac, you will be more interested in ATI's CrossFire technology. Since, if Apple does not decide to adopt NVIDIA chipsets, which is likely, then SLI will never be available on the Mac, since NVIDIA refuses to license the technology to competitors.
On the other hand, ATI has voluntarily licensed it's technology to Intel.
