I am intending to vectorize an FE code using CUDA/OpenCL. I am going to be out of the office whilst doing this development work so it would be very convenient if I could find a suitably capable laptop machine.

I was considering an Alienware M17X with a GTX 280m but I now see that this isn’t actually based on the GTX280 - Is it capable of Double Precision Arithmetic?

Is there a mobile NVIDIA graphics card capable of 64-bit arithmetic using CUDA/OpenCL?

The NVIDIA web page for the GTX 280M links to the DELL site for the Alienware M17X, when I try to configure it it only has the option of ATI 4870 graphics. Would that give DP arithmetic with OpenCL?
