It seems that with this technology and with Snow Leopard coming out that this should be a no brainer. However, the recent refresh has shown little signs of picking this up. The Mac Pro has had multi gpu options for a while so nothing new there, but the iMac didn't get anything in the way of multi GPUs. So with the Mac Pro and the MBPro having multi GPUs, it may just be that their saving it for their pro line. Since Snow Leopard is supposed to bring about OpenCL which will use the GPU, why have we heard nothing about SLI or Crossfire? These would greatly benefit the system. It seems to me that Apple could benefit greatly from using this technology, not just for the OS, but for a better hardware position. Thoughts?
