It's a cute small card, with a nice little heat-sink and was immediately recognized by nvidia-kernel. As 6200 and not 6200AX, but the benchmarks tell, that the power gets used.

640x480 - low detail - all effects - 0x AA - 0x AF
41.5 fps - min. 19fps - max. ca. 100fps
640x480 - medium detail - all effects - 8x AA - 2x AF
41.8 fps - min. 19fps - max. ca. 100fps
640x480 - high detail - all effects - 8x AA - 0x AF
26.7 fps - min. 12 fps - max. ca. 50 fps(?)
I think, that's fair enough for a completely silent card. :)
x.org 6.8 KDE with xcompmgr still crashes on me though.
