The budget market is amess.
Since the 8500LE, ATI has released the 9000,9100,9200 - all either slower or identical. And 3rd party vendors are actually releasing even lower-clocked versions.
Nvidia came out with the 4 MX which can't do even minimal pixel shading, and some of them have crippling SDRAM. And now there's the FX5200 -not exactly a speedster anyhow- being released in carefully concealed 64-bit versions.
