Unigene released their Heaven v1.0 benchmark at about the same time Windows 7 was officially released, and it is an entertaining way to analyze the DirectX 11 performance of compatible graphics cards on this operating system. This test is being included in here just to see if the DirectX 11 gaming performance is influenced by either motherboard, or by the roughly 50% overclock.
The first graph shows the "Scores" portion of the results from Heaven v1.0, and right away you it is clear that overclocking the processor has minimal impact on this test. I'd consider the results to be close enough to easily be covered by a margin of error.
The second set of results from this test detail the FPS, or the frames per second that the test averaged. You do see a slight increase from the Gigabyte board to the ASUS board, and then another slight bump while overclocked, but there would be no way to see that in real life.
