While I share "JustAnEngineer's" reservations about PCIe 3.0 mobos being compatable with Ivy Bridge cpu's, especially when that generally hasn't been the trend in the past for Intel. I can't help but point out that there must be some reason why all major mobo manufacturers are coming out with gen3 products especially when sandbridge cpu's do not have gen3 capabilities. They must know something about future compatability of Ivy Bridge. Whether thats true or not...thats up to the eyes of the beholder, but for roughly the same price you can have the "possibility" of being compatable with Ivy Bridge. That must count for something.
