Frankly, we were shocked at the difference in performance between the two top-of-the-line, next-generation cards. The 256MB ATI Radeon X800 XT Platinum Edition trounced Nvidia's new GeForce 6800 Ultra so soundly in our tests that there is no longer any question: ATI's new graphics card is the best product of its kind.
Yet the benchmarks they post show that the X800 "trounces" the 6800 by all of 0.2 FPS in 'Splinter Cell' and in 'Microsoft Flight Simulator 2004' the 6800 actually wins in some settings. In UT2003 fly-by both cards get over 100FPS at 1600x1200 with 4xAA and 8xAF which should be enough for anyone! OK, the XT does a little better at higher resolutions with AA/AF, but by no stretch of the imagination is the difference "shocking". It's nothing like the way the 98000 beat the NV3.x cards, which was amazing.
There's no disputing the X800 is an amazing card, but the performance gap isn't anywhere near as vast as the CNet leader would have you believe. Then again their software reviews have always been awful, so I'm not suprised...
