I was disappointed by the fact that my GeForce 4Ti (a DX8 hardware card) gets better framerates, even on some DX9 tasks, though.
That makes sense. All of the Ti series are clocked faster (The Ti4200 at about the same, though) and have more memory bandwidth than the FX5200. It's not really a fair comparison, though, as the Ti series were the mid to high end cards, while the FX5200 is the ultimate low end, equivalent to the MX's of the GeForce 4 series.
--Edit--
Nice chart
here, btw.
