The Gigabyte GA-X79-UD5 can be had at Newegg for ~$339.
I was going to build a Core i7 3930K / X79 (likely GA-X79-UD5) as soon as they started to ship. I noticed ASUS and MSI seemed to be first out of the gate with motherboard availability. Anyway, I decided to wait at least for the C2 stepping as it seems that VT-d hardware support isn't functional in C1 stepping.
Also, there was no Intel SRT (although ASUS has their own implementation), no SAS, missing SATA Ports (most boards were going to have 14 SATA ports) and so on.
Basically there are missing features and this was done to get the platform out the door in Q4 2011. Think P67 vs Z68 chipset. The P67 looked rushed if you think about the recall and the added features of Z68.
I'll wait a bit,....
Fix it first,....
Then I'll bite,....
Q1 or Q2 2012,...
