3D Video Card Hierarchy?

I saw on a forum once before someone had listed all of the video cards since the original Voodoo card to video cards of today and had them in order of performance (no benchmark numbers, just rated in order). Does anyone have anything like that? I just bought a Geforce2 card for $30 for my girlfriend's PC so she can play games and it appears to be incompatible with her Dell Optiplex GX1p. I want to get another type of card for her, but am unsure of the performace of legacy cards. I'd like to keep it under $50 (closer to $30 would be better) and someone mentioned something about the ATI cards. Can anyone give me a hand? Thanks,

Keith

this is the only one I know of, if anybody can find a better one I'd like to see it

Geforce 2 GTS/PRO/TI - Voodoo 5 5500
Voodoo5 6000 (had 128 mb DDR and claimed that it had 12GB memory bandwidth! The GF 4 cant do that now)
Geforce 4 MX 420
Geforce 4 MX 440
Geforce 4 MX 460
Geforce 3 Ti 200
Geforce 3
Geforce 3 Ti 500 - Radeon 8500
Geforce 4 Ti 4200
Geforce 4 Ti 4400
Geforce 4 Ti 4600

Where do the ATI's fit in Radical? I was looking at a 7000 and a 7500.

I havent used the 7000 or the 7500 much, but from what I read and the little experience that I have with them, the 7000 sits slightly over the GF2 and the 7500 is sitting with the low end GF 3
