NVidia GTX 660Ti SLI Performance and Overclocking

There are six tests in 3DMark 11. The four graphics tests use advanced rendering techniques to compile the scene including tessellation, volumetric lighting, depth of field and post processing effects. The physics test uses rigid body simulation to stress the CPU while the combined test features CPU and GPU workloads. The CPU handles rigid-body physics while the GPU is tasked with volumetric lighting, tessellation, post processing as well as simulating soft-body physics using DirectCompute.

Clockspeed is everything when it comes to DX11 benchmarks.  Due to the nature of how DX11 is processed almost everything is offloaded to the GPU leaving the base system available to handle game data.  3DMark 11 does have a physics and combined test but for our benchmark results we only care about the GPU score.
