ASUS Rampage III(Both Extreme and Formula) is one of the most expensive and best OC'er in X58 motherboards.So unless you need their extra feature and a huge OC'ng potential,buy them;otherwise,all of Saint 19's recommendations are excellent.
AMD chipsets support CF only.So if you are planing to run SLI,then go with an Intel board.They're better for SLI support(compared to AMD Nvidia chipsets)
