JJ i don't want to go in off with this thread, I'll just repeat facts: only MT-able LAME build was Intel's 3.97a... all community supported builds (including the latest 3.98 beta, a re NOT multithreaded! What's true is that each build is compiled with latest Intel's compilers and they're faster with each build, but they are not multithreaded.

Speaking about photoshop, smome filters, and some picture manipulation algorithms are multithreaded, but not majority! Thus why PS is only partially multithreaded. regarding the iTunes, as you shown it can't see beyond two cores, so we can go on and argue about meaning of "multi" in multithreading...

as a word of advice, don't use taskman and don't run games in window to track load on CPU! Use RivaTuner logging ability and time graph!
