I've read on HardOCP.com that the Nvidia reference boards, including the EVGA, have real problems. Apparently SATA HDDs get corrupted. A Nvidia rep who was interviewed by the site acknowledges the problem and they have released a beta BIOs with a final one coming soon. However, users who have already experienced corruption will still have to reinstall their OS. According to the Nvidia rep, this problem doesn't affect the Asus n680i boards.
