When it comes to gaming the GeForce GTX 285 is the primary limitation at 2560x1600, which is why we also test at 1024x768. Using Unreal Tournament 3 for our test, all four test configurations delivered 110fps at 2560x1600. At 1024x768 the Phenom II X4 955 system rendered just 182fps, while the Asus P6T Deluxe managed 230fps and the MSI X58 Pro-E 239fps.
The Asus P6T Deluxe was a bit faster than the X58 Pro-E Deluxe in Enemy Territory Quake Wars at both the tested resolutions. Similar results were presented when testing with Far Cry 2, though one way or the other this will hardly represent a gain or loss in a real gaming scenario. What we are trying to establish here is the stability of the platform.
You may have also noticed that the Phenom II X4 955 processor is faster than the Core i7 965 Extreme Edition in Far Cry 2.
