I like the fact that it has an external COM port. Do these NICs support PTPv2? Is so, then even though 2.5Gbe is overkill, a simple serial GPS with PPS, and dedicated PTPv2 links to your few servers, and you have a cheap solution that will keep your servers within 1-10 μs of each other.

A dedicated solution with a supporting switch will do that, too, but that would set you back many thousands.
