MSI R7850 Power Edition OC Video Card Review

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.

The numbers to watch in all of these tests will be the battle between the Radeon 7850 and GTX 580.  Granted this is an older generation video card but should help to illustrate the performance.
 
As the numbers show the MSI R7850 Power Edition OC is a close second.
