Is it a good idea to start a sandy bridge build now?

1st ones should hit Sunday-Monday ..... the adventurous types among us will have their builds OC settings locked in by Tuesday .... those unwilling to jump on the bleeding edge or those waiting for "Revision A" to p thru the channel in hopes of advantages developed through refined manufacturing and more mature BIOS's will start building in March. so is it really a good idea to start sandy bridge build now? or should I wait two more months?
