Motherboards.org posted a review on the Intel Core 2 Extreme QX6850 processor

Intel has dominated the playing field of CPU technology for the last two decades, and even though rival company AMD for awhile stole some of their fire with their FX series CPUs, Intel is once again leading the pack, and without competition. Really the two main things of focus on the QX6850 are the new faster FSB speeds and the amount of L2 Cache that the chip has to offer. Like the Intel rep says himself these are just speed bumps in our CPU lineup, but nice ones nonetheless. We will have the full review up later today, but here is a taste of Intel's latest flavor.
