I don't think anyone here wants to spend upwards to $1k for a mobile CPU. I know I wouldn't want or need to, unless I was building a gaming laptop...and even then, the QX9300 seems a bit of overkill for a laptop.
As for whether or not the QX9300 will work with the Clevo M860TU, I think it depends on the chipset being used, and whether or not the QX9300 will need a different voltage regulator setup or not.
