AIW Radeon vs GeForce2

I am currently using a GeForce2GTS video card and am looking to upgrade to an ATI All-in-Wonder card for the TV-tuner support.

I have not been able to find any comparison information between the GeForce2 cards and the AIW Radeons. I’m not looking for top of the line, I just want to make sure the card I move to isn’t going to perform any slower than the one I already have.

Basically, I’m looking for a 3D performance comparison between these cards:
ATI All-In-Wonder Radeon 7500
ATI All-In-Wonder Radeon 8500
ATI All-In-Wonder Radeon 8500DV
nVidia GeForce2 GTS

Does anyone have any info on how these cards compare?
