I can't really help you with the AMD motherboard, dont get much chance to
work with them at Intel :) However, I wondered exactly what NIC you have?

And have you tried taking the tip of tree driver, Scott and others have been
hard at work tweaking it. I can't swear that we are 100% yet, but you
should give that a try before a whole motherboard swap :)
