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

The GeForce 6800 XT was released over a year more recently than the GeForce FX 5900XT, 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 GeForce FX 5900XT.

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 6800 XT has 128 MB more video memory than the GeForce FX 5900XT, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 6800 XT also has superior memory performance overall.

The memory bandwidth of the GeForce FX 5900XT and the GeForce 6800 XT are the same, which means the GeForce FX 5900XT and the GeForce 6800 XT have equal limitations when it comes to graphical data transfer.

The GeForce FX 5900XT has 4 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the GeForce FX 5900XT 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 GeForce FX 5900XT performs better when taking into account other relevant data.

The GeForce FX 5900XT requires 35 Watts to run but there is no entry for the GeForce 6800 XT.
