I just ordered 2 of these
http://usa.aopen.com/Products/mb/AK77-600N.htm from neweggs refurb section for $US28.00 each. Sounds like a decent board. Should get them at the end of the week. Monday headed to Chula Vista California for a few weeks.. Hoping these boards will get in Friday so I can get some more data. These boards appear to have some decent overclocking ability so I can try and up the wattage some.
I also have an older XP1600+ that has a much larger die on it that the XP1700+ I am using now. Might try that chip to...
