3DMark 11 is the latest version of the world’s most popular benchmark for measuring the 3D graphics performance of gaming PCs. 3DMark 11 uses a native DirectX 11 engine designed to make extensive use of all the new features in DirectX 11, including tessellation, compute shaders and multi-threading.
3Dmark11 Testing was performed while using the performance preset, with the AMD Radeon 6970 video card(s) Control Panel set to default settings.
Since that again I am testing 3 very different computer platforms, and the fact that 3Dmark11 will vary from one test to the next, I am going to say that the performance of all of the tested motherboards is on par with one another. I will have to add this though, the P8P67 EVO and the P9X79 Deluxe motherboard platforms consistently kept out performing the Rampage II Extreme motherboard with the Core i7 970 CPU.
