can't say anything on being legit. make sure you guys "post" your source ._.
but the 9th core probably has something to do with proper mutlithreading. by my understand, with intel, it basically tells a core 2 commands, 1 is its primary and the second is ....well, it's secondary. When there is "free time" with thread #1 it starts calculating thread #2? -- is that how it works?
the 9th core probably monitors the other cores, and when any of the cores are not doing anything it offloads an extra thread to that specific core? -- though I'm reading the thread now and I may be so wrong. haha
