Well the title is alarmist.
That article just states Gigabytes claims, it doesn't even lean one way or another, just echos and quotes their technical team, doesn't even give any Asus counter arguements or anything (i expect in the next few days there will be an identical type 'news' article from ASUS).
I wouldn't base my purchasing on fluff like that, i have had several ASUS boards over the years and all have been great. Im not one for falling in love with a manufacturer though, i'd happily take a diff mobo if it performed better.
Cant even call this an article, it's just a bunch of quotes till right at the end when it mentions "In related news, TG Daily has story about the Gigabyte event, but in an entirely different light. Apparently, an editor from a well known website made way with confidential Gigabyte information, and TG Daily was told that the editor cabbed straight to Asus’ headquarters with sensitive Gigabyte data. This act alone makes things more difficult for all parties, especially those hosting and those attending events like these down the line."
That they got from a different source!
