The Inquirer observed some of the just released 3DMark06 benchmarks and reports NVIDIA is winning in almost every scenario over most of ATI's offerings - albeit mostly not by a huge difference.
Hard to get Geforce 7800 GTX 512 wins over X1800XT, an SLI 7800 GTX 512 is winning over X1800XT Crossfire. Again, the 7800 GT is faster than X1800XL and last but not least the Geforce 6800GS is winning over X1600XT.
At this point it is a total Nvidia's dominance but we know that situation will likely to change as soon as Monday. Nvidia might lose at least in a few of these scores as ATI has a new X1900XTX and XT cards plus a Crossfire based X1900 XT card to launch.
