Testing:

Several of the boards in this roundup have the ability to use up to three or four video cards in a multi-GPU setup using both NVIDIA and AMD based cards. So what better time to see just how well a socket 1155 Sandybridge based system does with this type of graphics setup. Sure it's overkill as most people will not step up to the plate and purchase a system of this caliber but inquiring minds would like to know. For this comparison I will be using both 3DMark Vantage and 3DMark 11, Lost Planet 2, Metro 2033 and Aliens vs. Predator as my benchmarks of choice. The video cards used are three ASUS GTX 570s and three Sapphire HD 6970s. Scaling will be tested going from one to three cards at resolutions of 1680 x 1050 to 2560 x 1600. The control panel settings for each manufacture will be left at the default settings with the exception of the application of anti-aliasing and anisotropic filtering listed for each test. PhysX is disabled for 3DMark Vantage. The processor will be overclocked to 4.5GHz (100x 45) to try and eliminate any CPU bottlenecks from occurring in these benchmarks.

Testing Setup:


 

Aliens vs. Predator:

  • 4xAA
  • 16x AF
  • Very High
     

   

 

3DMark Vantage

  • Default test settings
  • Performance, High and Extreme Preset

   

 

Lost Planet 2:

  • DX 11
  • Benchmark B
  • High
  • 4xAA
  • 16xAF
  • 1680x1050, 1920x1200, 2560x1600

   

 

3DMark 11

  • Default test settings
  • Entry,Performanceand Extreme Preset

   

 

Metro 2033:

  • DX11
  • High
  • DOF On
  • 4x AA in CP
  • 16xAF in CP
  • AAA

 

   

 

First off this test was not about seeing which card offers higher performance, but to show how well the scaling is when you add video cards to the system to create a dual or triple card setup as this is one of the features of most of these boards. Throughout the benchmarks, the addition of another card created scaling in almost every instance. The exceptions were adding a second HD6970 in Metro 2033 where the single and dual card AMD setup resulted in identical performance while three cards did scale. Whichever multi-GPU setup you choose, you will see linear scaling in almost all instances with both AMD and NVIDIA cards.
