Yeah, but at the very end of the article it states:
With low frequencies and without Turbo Core, the new eight-core Phenom II X8 will likely be considerably slower than the existing six-core Phenom II X8 processors based on Thuban design.
AMD, ECS and Jetway did not comment on the news-story.
Which means for games it's performance will be pretty low. It will only benefit those types of programs that can actually make use of 8 core like video encoding. Of course, you then have to take into consideration what's better the 8 core Phenom II X8 with slower clockspeeds or the Phenom II X6 with 2 fewer cores, but higher clockspeeds.
Most games only use 2 cores. More games capable of using 3 or 4 cores will be coming out, but will be relatively small in proportion within the overall gaming market.
