It is quite likely that in the next year or two we will be releasing versions
that have GPU support, so getting a card with a reasonable amount of RAM would
be a good idea

External Email - Use Caution
FreeSurfer does not require any special graphics card, you can chose whatever
card you like (as long as it works under Linux, but I haven't come across one
that did not in the last 10 years or so).
*If* you want to run stuff on the GPU (the current FreeSurfer version does not
support it afaik, but maybe you have other use cases), an Nvidia card may be
better because from what I am seeing, CUDA seems to be more widely used than
OpenCL. If you do not care about CUDA or have never used it, chances are high
you can completely ignore this.
