"Q: Does CUDA support Double Precision Floating Point arithmetic?

 A: CUDA supports the C "double" data type.  However on G80
    (e.g. GeForce 8800) GPUs, these types will get demoted to 32-bit
    floats.  NVIDIA GPUs supporting double precision in hardware will
    become available in late 2007."

My guess is that where NVidia goes ATI has already gone or is not far
behind.
