3DMark 11 is the latest version of the world's most popular benchmark. Designed to measure your PC's gaming performance 3DMark 11 makes extensive use of all the new features in DirectX 11 including tessellation, compute shaders and multi-threading. Trusted by gamers worldwide to give accurate and unbiased results, 3DMark 11 is the best way to consistently and reliably test DirectX 11 under game-like loads.
It comes as no surprise that the 3DMark 11 score for this DIY AIO is extremely low. You really can't compare the Intel HD 4000 series graphics to a standalone video card, much less one like the GTX 580.
It helps give you an idea of where we stand in 3DMark 11, though, nonetheless.
