3DMark05's main test is almost entirely limited by the graphics card, as is obvious. Again, the integrated graphics solutions managed to make it through a DirectX 9 game without crashing, although they're many times slower than the GeForce 6800 GT when dealing with this crushing graphics load.
The CPU tests are intended to show us something more about general system performance, and here, the Radeon Xpress 200 falls behind the K8T800 Pro. I'm curious about whether the bridge chip on our PCI Express GeForce 6800 GT isn't causing some of the performance drop-off. I will have to test with some native PCI Express graphics solutions and find out... in my next chipset review.
