Check that bad boy out. You are looking at the GA-X58A-UD7 (former know as GA-EX58-EXTREME 2). As you noticed, Gigabyte have given the new board a name change to avoid confusion with their previous GA-EX58 Extreme, this board was originally going to be a revision of that board, however it features a drastically changed feature set so I see this as a wise move on Gigabytes part.
Gigabyte have re-labeled their board the GA-X58A-UD7 and it looks pretty much the same as the GA-EX58 Extreme 2 board in my previous article. Gigabyte has only released these two teaser pics so far. Pricing and release date are still TBA -- yeah likely before Christmas.
