You are right, it's not scaling very good over 4.5-4.6GHz. I don't know why, maybe some internal throttling mechanism, OVP, OCP, or something.
But we must remember that we are giving those chips up to 20% more voltage then absolute max recommended.
Here is the scaling from my experience 4560MHz/100GFLOPS, 4800MHz/103GFLOPS, 4900MHz/105GFLOPS, 5000MHz/107GFLOPS (an you won't see this picture, cause I never managed to pass all 20 loops )

No they would not, they would be the same. There are many topics about running higher BCLK with lower multis or lower BCLK with higher multis.
Common conclusion is that there is no difference if clocks are the same (or very similar).
