For this next batch of tests, we ran Kribibench v1.1, a 3D rendering benchmark produced by the folks at Adept Development. Kribibench is an SSE aware software renderer where a 3D model is rendered and animated by the host CPU and the average frame rate is reported.
We used two of the included models with this benchmark: a "Sponge Explode" model consisting of over 19.2 million polygons and the test suite's "Ultra" model that is comprised of over 16 billion polys.
The Intel D975XBX2 motherboard had a marked edge over the nForce 680i SLI motherboards in both Kribibench tests that we ran. The Gigabyte GA-N680SLI-DQ6 outpaced EVGA's nForce 680i SLI-based motherboard in both tests, but it trailed the Intel-powered mobo.
