To prevent GPU Boost (NVIDIA's adaptive throttling mechanism) from interfering with the clocks, we need to change this setting in the Nvidia Control Panel.
As we can see from the above benchmarks, the ASUS 670 DirectCU II actually is head to head and sometimes ahead of its more prestigious competition at stock and when overclocked. Having said that, the other cards still have significant overclocking headroom though, but they cost more.
