I find The z77 is the best choice two it even has pcie 3.0 my choice would be this one http://www.newegg.ca/Product/Product.aspx?Item=N82E16813131850
discontinued and you pay a premium for thunderbolt (which is irrelevant)
you could always go a tad cheaper and get the same MoBo that i have (in signature). works fantastically. has a shed load of usb 3.0 ports, integrated graphics (good if your gpu goes down), dual ufei bios, backup bios in case your main gets corrupted and comfortable overclocking capabilites. the manufacturer also has decent support.
