I would take a T9600, T9800, T9900, P9500, P9700, x9100 and QX9300 over a Q9000. Lots to choose from! The Q9000 doesn't OC well and has less cache than the other quad cores. It's probably one of the last procs I would choose. The qx9300 benchmarks will blow the q9000 out of the water. Like I said not much of a comparison.
Speaking of OC'ing have you played around with it yet Dave?
Less than a week my Slot Drive DVD has crapped - AW is dispatching a new one. Interestingly enough I told them I would install myself since i am on the road for the next few weeks, but told me a technician had to install it lol.
