As to be expected. I'm still waiting for Techreport's review, but it almost a lock for me to go with this card.
This card will not overclock much higher for the simple reason that Gigabyte pretty much went all the way for you, they defined a factory tweak and applied it. It is roughly your maximum with maybe ~40 MHz room left on that GPU base clock frequency. As such at default this card hovers in that familiar 2000~2050 MHz range.
