If you can go up to $200, the Asus Maximus VII Hero is the best choice. The Maximus VI is cheaper too, but you will have to do a bios update, which is easy with ROG board, you just plug in a USB flash drive with the bios on it, in the designated usb port.
But if you want to get something cheaper, I would suggest an Asrock z97 Extreme4 or MSI z97 Gaming 5.
