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.
MSI's Gaming X Plus is up against one of the highest-clocked GTX 1080s around, the EVGA FTW. The increase in core frequency gives the EVGA card the upper hand in 3DMark's full-HD test, but at higher resolutions the quicker memory allows the MSI to take the lead.
