Yes, that could be an option, it has half the efficiency on FP32, but 4 times higher on FP64. Disadvantage is, that there is no fan and you have to build your own solution for that because it's a server-card. Or am I wrong?

Sorry for taking so long to respond, as it is passively cooled it will require the airflow of the front fans to blow air through, I have been looking to get a few for my server case build, but I am unsure of performance on a standard case.

You raise a very good point though
