In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are significantly better than the AMD Radeon X1900 Series.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 3800 was released over a year more recently than the Radeon X1900 Series, and so the HD 3800 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon X1900 Series.

The HD 3800 has 256 MB more video memory than the Radeon X1900 Series, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the Radeon X1900 Series has superior memory performance.

The Radeon X1900 Series has 64 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the Radeon X1900 Series is much better than the HD 3800.

The Radeon X1900 Series has 36 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the Radeon X1900 Series is 13 and the actual shader performance of the HD 3800 is 0. The Radeon X1900 Series having 13 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon X1900 Series delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

We would recommend a PSU with at least 520 Watts for the Radeon X1900 Series.
