I am looking at choice of the lower end fermi cards and I was wondering if you could comment of Freesurfer's ability to take advantage of some seldom used functions included in nVidia GTX 400 (including tesselation) that were stripped down from nVidia GF104 chipset.

I'm not aware of any issues with these cards which affect CUDA. In most cases, the primary bottleneck in my ports is the rearrangement of data for the GPU, so the card itself is less important (provided it has enough RAM). As another reply said, right now, we're targetting CUDA Compute 1.1, which is substantially pre-Fermi.
