Does anyone know where this system stands performance wise vs classical computers? Are there types of problems where this is known to be faster now? Or are we still waiting for more qubits for that to happen? Thanks!

Not yet. This is commonly called "quantum advantage" or "quantum supremacy", i.e. proof that on a certain (even artificial and with no practical applications) problem a quantum computer can perform better than classical state-of-the-art. So far even for the task of simulating quantum circuits (which quantum computer should definitely be better at!) we don't have enough cubits to have a go at quantum advantage.
Depending on connectivity (full connectivity like on ionQ vs planar connectivity like IBM / Rigetti), we need between 100-200 and thousands of qubits to show quantum advantage (denser connectivity -> lower qubit number requirement). And that's just for a synthetic problem with no applications.
