I hope you did not purchase that P67 MOBO yet. If so, your best bet is to obtain and refund or wait until the vendor offers a replacement MB sometime in April.
I recommend you NOT build your Sandy Bridge rig just yet because Intel recently released a report of a major flaw in their chips on the new P67 MOBO's. You can read about it here:
Intel Identifies Chipset Design Error, Implementing Solution
The SATA II controllers are prone to fail.
Most motherboard manufacturers are saying they will not be releasing the new mobos until late April.
You may want to wait.
