Intel didn't certify drivers for these cards on 2012 or W8 and I'm not interested in buying new NICs (at enterprise/server grade prices) for a development environment.

Has anyone gotten them to work properly?

I also have a bunch of MT NICs as well but those are really old so I'm not worried about those but the PT NICs are the biggest thing I'd like to get working (duals on W8 and quads on 2012).
