Rage3D has published a review on the NVIDIA GeForce 7800GTX video card

The NV4x based 6-series cards, released 15 months ago, started nVidia off on a new path that would help rebuild a reputation that took a serious beating after their failed NV30 5-series line. The 6-series introduced new features and improved performance over the previous generation so much so that people realized how serious nVidia was about reclaiming the performance and features crown that ATI managed to wrest from them in the summer of 2002. While the battle between nVidia's 6-series and ATI's X-series was often bloody, brutal, and sometimes downright ugly, it reached a clear conclusion when nVidia launched the 7800GTX onto the battlefield. No more is it 6800 vs. X800, it's now 7800 vs. X800 and as you'll see in this review, that's a battle ATI has no chance to win.
