NVIDIA nForce 780a SLI Motherboard Round-Up
Cinebench R10 and 3DMark06
Cinebench R10 is an OpenGL 3D rendering performance test based on Cinema 4D. Cinema 4D from Maxon is a 3D rendering and animation tool suite used by 3D animation houses and producers like Sony Animation and many others. It's very demanding of system processor resources and is an excellent gauge of pure computational throughput.

This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The time it took each test system to render the entire scene is represented in the graph below, listed in seconds.
Cinebench R10 showed very little variation between the AMD-powered systems. And, once again, using the IGP had only a marginal - if any - impact on performance.

3DMark06's built-in CPU test is a multi-threaded DirectX gaming metric that's useful for comparing relative performance between similarly equipped systems. This test consists of two different 3D scenes that are processed with a software renderer that is dependent on the host CPU's performance. Calculations that are normally reserved for your 3D accelerator are instead sent to the CPU for processing and rendering. The frame-rate generated in each test is used to determine the final score.
3DMark06 tells essentially the same story as Cinebench and the Kribibench results on the previous page. The various nForce 780a SLI boards we tested all performed similarly, as did the AMD 790FX. And using the IGP had very little impact on performance - at least in this test.
