Ok... what you need to know. Right now, there is a promotion going on with EVGA that if you own a 680i motherboard, you can upgrade to the 780i for $80 (This includes hipping and handling). I have no idea if that is cost efficient or what. http://www.evga.com/680iupgrade/
This promotion could also be causing the slow flow of 780i motherboards. As they make them, they have to send them to the users who have preorder them through the promotion.
o1die - Why on earth would people complain if nothing was wrong with their board?. You normally only hear the negative things about products but rarely hear the good things. From all the reviews that I have read about the 680i chipset, they all said it is a rock solid chipset. I would only assume that this carries over to the 780i chipset. The only real differences between the two are the support for PCIe 2.0 and the ability to run any 45nm quad line from Intel. Not to mention that it is PCIe 2.0 x3 all x16 slots.
