3DMark
3DMark 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 JetStream's GPU Boosting tricks enable it to pull ahead of the Radeon HD 7970 GHz. Palit's card is some 15 per cent faster than a standard GTX 680, too.
