If you've got a Geforce3, you've really got nothing to complain about. Sure, the G4 Ti4200 is out now, and it's faster, but not by that much. The G3 Ti500 is still an amazingly good card for gamers, and should keep you happy for a long time. There isn't anything coming out anytime soon that you won't be able to run with that card, I don't think there's much of a reason to upgrade to a G4, except just to say that you did. Wait around at least until NV30, nvidia's next generation gpu.
