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.
There's not much in it for those looking to spend not a penny more than £200. The EVGA GTX 1060 SC Gaming and Sapphire Nitro RX 480 4GB are practically neck and neck.
