In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 XT are noticeably better than the Nvidia GeForce FX 5900 Ultra.

The GeForce 6800 XT was released over a year more recently than the FX 5900, and so the GeForce 6800 XT is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the FX 5900.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce FX 5900 Ultra and the GeForce 6800 XT have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The FX 5900 has 2.4 GB/sec greater memory bandwidth than the GeForce 6800 XT, which means that the memory performance of the FX 5900 is marginally better than the GeForce 6800 XT.

The GeForce FX 5900 Ultra has 4 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the FX 5900 is 2 and the actual shader performance of the GeForce 6800 XT is 4. The GeForce 6800 XT having 2 better shader performance is not particularly notable, as altogether the FX 5900 performs better when taking into account other relevant data.

The GeForce FX 5900 Ultra requires 59 Watts to run but there is no entry for the GeForce 6800 XT.
