Apparently ChipHell has accused NVIDIA of using marketing shills in its forums and, according to the site owners, they had to ban all the accounts spreading the anti-AMD rhetoric. Hit the link for the complete run-down. Thanks to [H] forum member xoleras for the heads up.
Rough chinese translation. ALL of the posts related to kepler being 299$ from chiphell, and speculated performance, were from marketing shills (proven by the owners of the forum) and have been banned. Charlie from SA was bamboozled as well. Keep it classy Nvidia.
