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.
It's starting to look congested in the £100-£120 market. Gigabyte's WindForce card is a hair faster than reference, resulting in a 3 per cent increase in 3DMark performance.
