Ok so here is some more info for you guys, as i was there and i had a hands on with these boards as much as i wanted and they answered all the questions.
Some VERY surprising things, the G1 Sniper 3, the Z77x-UD3, and the Z77X-UD5 ALL have POST Code displays, voltage read points, and buttons for power, reset, and clear CMOS. This time GB is adding those features which aren't too hard to implement into a wider range of boards.
The G1 Sniper 3 uses a PCI-E bridge chip, but it isn't an NF200 and it is PCI-E 3.0 compatible to supply that kind of SLI.
The new Atheros NIC, is the next gen bigfoot NIC, it still hasn't been publicly announced. The Sniper 3 also uses another Intel NIC. the UD5 has 2 Intel NICs. It also seems the other boards are using the Intel NICs for the most part.
What is most interesting is GB way of diversifying the product lineup. I was at CES, and GB held a "meet the executives type meeting" in which these boards were unveiled. A few of GB's executives actually love overclocking! I was able to talk to them one on one about their boards and how they could make them better, they definitely listened to everything I or others at the event had to say. GB does listen, even to things users say in this thread.
I made a video too, but I couldn't upload it yet. But those etecknics guys were nice.
The issue is why do you need a UD7 when the UD5 has all the features older UD7s had? All these boards carry OC style features except multiplier buttons. BTW hint of GOOC was about. .
