Hi Tech Legion posted a review on the Intel Core I7 920 Processor

What the Enthusiast needs to know about the Core I7 is that there is a lot of headroom to overclock. Most important is you don't have to have the most expensive processor to get great "Enthusiast Value". The motherboard used for this review was not an extreme edition X58, it was an entry level Gigabyte board - the one without all the bells and whistles. The processor used was the 920, which is the mainstream entry of the Core I7 processor. If it wasn't for my heatsink limitations, I'm sure I would have topped the 4GHz mark.
