Beyond what clock rate would an i5 2500k's cache start to bottleneck?

[A Bad Day]

I've always wondered, beyond what clock rate would an i5 2500k's 6MB cache start to bottleneck the performance when gaming? I know that processors with large amount of cache ran around processors with smaller amount of cache in circles at high clock rates.

It won't. You can't push a 2500K far enough, even on water cooling, for that to become any kind of issue.
