3DMark Fire Strike
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.
It's round one to the GTX 1060 OC, which outdistances its red cousin by around 10 per cent at each resolution. Kind of makes sense given the 10 per cent price premium.
