"Like every other motherboard maker on the planet, ASUS maintains multiple product lines and inside each of these lines they have different vertical markets. For example, ASUS has their Republic of Gamers line that runs at the very top of the heap while their mainstream line runs with the tag of Extreme Phase or gets the Deluxe tag to denote extra features.
Recently we have been playing with the top of the line and have found them to be very capable indeed. Now, it is time to return to the mainstream; well, the upper end of the mainstream anyway. We are taking a look at the ASUS P6X58D-E. this $229.99 (at NewEgg.com) motherboard packs a bit of a punch for a decent price. With USB 3.0 and SATA 3.0, 16+ 2 power phases, SLI and Crossfire X support, it looks to be a very capable board indeed."
