i have no doubt your machine wont will be able to do the same 
Fixed for ya, assuming that is the meaning I interpreted from the context....

Nobody expects the Grammar Inquisition.
Anyway, I would say pretty much the same as S-99. NVidia's 7 series are good cards and since they make them for AGP as well, they are pretty much the best you can get for your PC. I suppose you'd get best performance increase/price ratio by increasing system RAM and getting a GeForce 7600GT or possibly GS if you're interested in even more of a budget card. Perhaps with even 512MB memory...

I myself have a PCI-E version of GF 7600GT with 256MB of memory and I have to say it's pretty good card in overall. It's the rest of my system that drags behind... I'm suspecting that my CPU ( AMD64 3200+ @ 2.0 GHz) with Venice cache just doesn't seem to manage to keep up with the GPU's information need or something.
