Benchmarks - 3DMark11
3DMark 11 is the latest version of this hugely-popular synthetic benchmark. Making use of DX11 features such as tessellation, compute shaders and multi-threading, it provides modern-day results and is available as a free download.
The Classified sits between the GeForce GTX 570 and 580 GPUs. For what it's worth on a synthetic benchmark, performance is comfortably higher than AMD's HD 7850 or HD 6950.
