3-Way SLI Comparisons
For our final set of benchmarks, we compared the 3-Way SLI performance of the new nForce 780i SLI to the nForce 680i SLI. In these tests, a trio of GeForce 8800 Ultra cards were installed in the two nForce powered test rigs, and some high resolution benchmarks with 3DMark06 and the DX10 version of Company of Heroes were run.
In both 3DMark06 and Company of Heroes, regardless of the resolution or test configuration, the nForce 780i SLI put up slightly better scores than the 680i SLI. As we mentioned earlier, although the NF200 chip doesn't have a full bandwidth link back to the northbridge, in most real-world scenarios performance likely won't be affected because the PCI Express 2.0 links for the graphics cards aren't being saturated.
