<p><span style="font-size: small;">In our series of X79 reviews, the next boards to face scrutiny are a pair of ASRock boards &ndash; the X79 Extreme4-M, one of the first mATX solutions to X79, and the X79 Extreme4, a full size ATX model. The main interesting point to consider starts with whether the power consumption and heat generation are applicable to the Sandy Bridge-E platform. With the socket and quad channel memory taking up serious PCB real estate, it is interesting to see how ASRock have tackled heat dissipation issues. We also compare the Extreme4-M to the Extreme4, its bigger brother.&nbsp; Both boards offer amazing value in X79 land, coming in at a recommended retail of $224.99 and $234.99 respectively.</span></p> <p><span style="font-size: small;"><a target="_blank" href="http://www.anandtech.com/show/5188/asrock-x79-extreme4m-and-x79-extreme4-review-sandy-bridgee-meets-matx">Read more...</a><br /> </span></p>
