I am a but curious that nothing was mentioned about the temperature

. This thing runs pretty hot. I have this CPU on a Asus G53SW and when I compile stuff on Gentoo like kernel, it easily reaches 80C, sometimes nearing 90s, even on this big chassis machine.
Of course, it is a very fast CPU. I mostly use "make -j4" -- I am still not very sold on the hyper-threading thing, besides I don't want my machine to run too hot, and leave some CPU left for doing other tasks while compiling too. Also, as I remember, the difference between "make -j4" and "make -j8" while running a "emerge -e world" was 13 hours versus 12 hours (using "genlop -p"), so probably just an hour here or there -- perhaps many ebuilds force single thread.
