In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7800 GT are very slightly better than the Nvidia GeForce 6800 Ultra.

The GeForce 7800 GT 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 GT and the GeForce 6800 Ultra have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 6800 Ultra has 3.2 GB/sec greater memory bandwidth than the GeForce 7800 GT, which means that the memory performance of the GeForce 6800 Ultra is marginally better than the GeForce 7800 GT.

The GeForce 7800 GT has 20 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the GeForce 7800 GT is 8 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce 6800 Ultra having 1 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 6800 Ultra delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 7800 GT.

The GeForce 7800 GT requires 65 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 GT. The GeForce 6800 Ultra requires 59 Watts more than the GeForce 7800 GT to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the GeForce 7800 GT.
