Bit-Tech published a review of Intel's Q9450 Quad-Core processor.

The wait for an affordable 45nm Quad-Core is now over, and the Q9450 promises to become the ultimate choice of the new offerings. It's not much slower than the QX9650, offers 12MB of cache and as expected, has some fantastic overclocking ability. How does 3.44GHz stable sound?
