Benchmark Reviews posted a review on the Gigabyte P55A-UD6 SATA-6G Motherboard

Computer hardware always evolves, and in the interest of making lives more productive technology continues to advance. Gigabyte has recently launched their P55-A series of motherboards on the Intel P55-Express chipset, which incorporate a new 3-3-3 theme of features: Super-Speed USB 3.0 and 3x the USB power output, as well as SATA-3.0 for 6Gbps bandwidth. In this article, Benchmark Reviews tests the Gigabyte GA-P55A-UD6 and inspects the new SATA-6G functionality in-depth. Performance will be measured between the Intel Core i7-860 fitted to the LGA1156 socket on the Gigabyte GA-P55A-UD6 motherboard and the Core i7-920 equipped GA-EX58-UD4P. Testing a Core i7-860 against an i7-920 might not seem fair, and it's a little biased to compare P55 against X58, but the final outcome might just surprise you.
