Some new info from OBR. This is something interesting to talk about, IMHO:

"Little secret: In Windows 8 (Development Release) is not Bulldozer chip as "8 Core - 8 Threads" but 4 Core - 8 Threads! AMD went out with the truth ! ! !"

IF Windows scheduler thinks this is an octo-core, and the threads go to whatever core is free, then you could have 4 threads running on 2 modules, which is far from optimal performance. Don't you think? It would be better to treat the CPU as a 4c/8t, the same way Intel HTT works.
