For our next set of tests, we moved on to some in-game benchmarking with the Crysis SP demo and Enemy Territory: Quake Wars. When testing processors with Crysis or ET:QW, we drop the resolution to 800x600, and reduce all of the in-game graphical options to their minimum values to isolate CPU and memory performance as much as possible. However, the in-game effects, which control the level of detail for the games' physics engines and particle systems, are left at their maximum values, since these actually do place some load on the CPU rather than GPU.
The Crysis CPU benchmark reported very similar scores for all three of the test systems, with the nForce 680i SLI finishing in the lead, followed very closely behind by the X38 and then the 780i SLI. Enemy Territory: Quake Wars, however, had a much larger spread. In the ET:QW benchmark, the X38 finished about 6.5 PFS ahead of the 680i SLI and 19.6 FPS, or about 13.1%, ahead of the 780i SLI.
