Recently i was looking at upgrading my 450mhz comp to a 850-1333mhz amd. I also figured i'd need to replace my v3 so looked at the geforce2. Then I saw a geforce 2 going cheap, and i had read before on a games sys reqs that stated, basically, you need more mhz if you have a v3, and less if you have a geforce. perfect. great way to squeeze a bit more out of my old work horse. So i bought the geforce 2 gts, and now I'm not even thinking about getting a newer system really, 72fps in halflife at 1200x1024 is good enough for me for another half year.
So yes, maybe a geforce 2 would do better in a faster machine, but it also takes a huge burden off of my machine and im squeezing a bit more life out of it!
Now i can play oni and project igi and soldier of fortune yay!
