Unfortunately, most recent FX5200 have a 64-bit wide memoryband limiting
them even more.

In short, yes. See
http://graphics.tomshardware.com/graphic/20040809/doom3-06.html for a
comparison under Windows (performance should be about the same for Linux
for the nVidia models). Do note that the FX5200 mentioned there is an
ultra model which is reportedly 50% faster than the non-ultra FX5200s.
Unless the TS has one of those ultras I think he got about the performance
he could expect. Maybe it could be upped to about 17-18 fps, but at
640x480, 32-bit colour and med-quality I would not expect more from a
non-ultra FX5200, especially if it has a 64-bit wide memoryband.
