If I were you I woud go for the ASUS P6X58D-E. This mobo has a great performance, overclocking very well, presents all the latest technologies, and is very stable. Moreover, the price is good. In my opinion, it's no necessary to go for the Premium. http://www.asus.com/product.aspx?P_ID=gFBKfNyhppW9tDbB&templete=2
As other people has said, the GIGABYTE GA-X58A-UD3R is another very good option. It's performance/price ratio is incredible.
There is an interesting article about this matter in this website:http://www.tomshardware.com/reviews/x58-usb-3.0-sata-6-gbps,2614.html
