ThinkComputers.org posted a review on the ASRock X58 Extreme3 Intel X58 Motherboard

The problem is the other new technologies that have just emerged, SATA 6 Gb/s and USB 3. Most of us had no idea that either was in the works when the Core i7/X58 emerged. Going to the expense of buying the new Core i7 980X, you definitely want the latest data transfer technologies, and with an older X58 board, the only way you will get them is with PCI expansion cards. But, the motherboard manufacturers are ready for this, and some have already released new models of X58 boards supporting SATA 6 Gb/s and USB 3. Today I will be looking at the ASRock X58 Extreme 3, their new top-of-the-line board. It not only supports SATA 6 Gb/s and USB 3, but also supports eSATA 6Gb/s. Read on to check out the ASRock X58 Extreme3!
