am quite happy with mine Asus Maximus VII Hero Intel Z97 had no problems with it,having said that the gigabyte offer looks very good to be true 2 for 1 but their is always an catch with these type of deals :
The new GIGABYTE warranty is intended to add a new product feature to all boards of the Z97 Black Edition line. Therefore, this product feature is connected to the life cycle of these boards.
Aside from all of this, GIGABYTE is free in their decision to change all kinds of voluntary features and services at any time without notice. so this offer can stop at anytime without notice leaving the 2 for 1 offer not variable
Following the conditions and terms for this upgrade service, the customer has to send the exchange board to GIAGYBTE with the original carton and all included accessories. In case that within the 3 years of usage for example, the customer loses a cable and or connector, GIGABYTE will handle the exchange in a fair and customer oriented matter. Even if the customer loses or presents the original carton in a less than suitable condition complete with missing accessories, GIGABYTE will find a fair solution in that singular case.this can mean anything from charges for missing or damage original carton
it is alway best to read the small prints,don't get me wrong gigabyte motherboards are good as i have had a few in the past
