I just looked back and it was an i7 920, and it could have sold for around $250. But it was a 2.66 GHz part running 130W. I really hope there is seriously good cooling involved because 3.8 GHz is absolutely pushing the limit on a 920.
BTW, the QPI on the 920 only has a 4.8 GT/s rate vs. 6.4 on the two high-end i7s and the several higher Xeons. So much for that amazing bandwidth.
I believe my QPI is around 7.2 GT/sec. I’d have to reboot and look. It’s clockable. Man, I really don’t want to call you an amateur again, so I won’t.

I think this is serious enough cooling. It sure beats having to waterproof everything when I used to freeze em to -35 c.
