Can anyone point to a chart that compares multiple generations of Radeons? I have an 1800 now and have been pondering a move to the 1950 or 1900 but none of the benchmarks have the comparison. At best they do 1900-1950 comparisons, or 19xx to nVidia comparisons, and benchmarks never go back more than one generation, which I find extremely annoying because I don't upgrade with each successive generation of video card.
TIA.
