I bought my X9000 for my laptop on EBay, cost about 320 GBP.
I've had it up to 3.4GHz too, amazing.
It shipped in a small wooden box, for protection.
It was however, an 'ES' version, meaning Engineering Sample. Due to this it does not report temp at all. That is not to say the laptops' fans don't clock up and down, just that using Core Temp and the like report garbage, or nothing at all.
I'm about to buy another 'ES' it would seem, an 920QX-M, for my new 8942G. Quite looking forward to it.
