In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7800 GTX are noticeably better than the Nvidia GeForce 6800 Ultra.

The GeForce 7800 GTX was released less than a year after the GeForce 6800 Ultra, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce 7800 GTX has 256 MB more video memory than the GeForce 6800 Ultra, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 7800 GTX also has superior memory performance overall.

The GeForce 7800 GTX has 19.2 GB/sec greater memory bandwidth than the GeForce 6800 Ultra, which means that the memory performance of the GeForce 7800 GTX is slightly better than the GeForce 6800 Ultra.

The GeForce 7800 GTX has 24 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the GeForce 7800 GTX is 13 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce 7800 GTX having 4 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 7800 GTX delivers a slightly smoother and more efficient experience when processing graphical data than the GeForce 6800 Ultra.

The GeForce 7800 GTX requires 108 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 400 Watts for the GeForce 7800 GTX. The GeForce 6800 Ultra requires 16 Watts more than the GeForce 7800 GTX to run. The difference is not significant enough for the GeForce 6800 Ultra to have a noticeably larger impact on your yearly electricity bills than the GeForce 7800 GTX.
