The CPUs are apparently for sale in various Chinese establishments and websites like coolaler.com and xfastest.com have users showing off their new wares in the appropriate forums.
Of course there is benchmarking and overclocking going on, but I don’t read much Chinese so…yah. Screenshots are universal however and see overclocks above 4.0 GHz this early is always a good sign for users HERE that will get them after the product officially launches.
