If I remember correctly, the Rampage II Extremes are around the same price as the P6X58D-E, and I would recommend the P6X58D Mobos. This one has USB 3.0 and 2x 6GB/s SATA connections (which makes a difference if you are going to use an SSD). It also has 3-way SLI, if you ever lose your mind and buy 3 vid cards.
