Tsunade is pretty damn strong though. Minato's strength isn't real strength but rather the insane Raijin+Rasengan combo. I also think that Tsunade isn't really comparable to other Kage because she's the first of a new class. We have Bruisers (First, Third, Seventh hokage) and assassins (Second, Fourth, Sixth hokage). Tsunade's the only one of her kind: utility. And the ability to heal an entire village during a war is quite powerful. Even other Kage fit in the same two Bruiser/Assassin category. The Raikage all seem to fall under Assassins (High single target damage) while the Kazekage all seem to be Bruisers ( high AoE jutsu).

I think that Kage level is really defined by:
 * ability to perform a variety of high-level jutsu
 * ability to do so often (high amount of chakra)
 * ability to analyze and apply strategy.

Hashirama (and hiruzen) by their nickname God of Shinobi seem to be post-kage, and in the former case post-biju level. Tobirama seems to be powerful but expected within the Kage level. The Sanin all seem to be post-kage level. Naruto is Post-biju level just like Sasuke. Their Six Paths power seems to be mostly gone, but during the final battle they were definitely Juubi level. Might Guy was, with the 8th gate, Juubi level but normally seems to be Kage. Kakashi seems to be around Kage level.

In this context, i think Sakura definitely is Kage level. However, i don't think she surpassed Tsunade, i think she's maybe matched her power but not exceeded it.
