$999 is a fully built computer, I think. And...
they have so many Q9450s at Microcenter that you can even order one... with overnight shipping... for $11 extra! Beware of the taxed-up price, though.
And... I have gone through two 45nm quad CPUs (Q9450 and X3350, its equivalence), four 45nm dual CPUs... and god knows how many more of the other types of CPUs...
