I don't understand what you are asking.
You say your card is fast enough. So why would you want to waste money on a new card? Keep it until it isn't fast enough, or overclock it, then get a new card. Then, when you need a new card, the GF4's will have dropped in price, and there may be other options as well then.
I don't wait 3 years between cards either. I wait 3 product cycles. Example: I had a Voodoo3. I replaced it with a GF2MX. I then replaced the MX with a GF3 Ti.
Would you "see" improvements? Probably not in resolutions below 1280x1024. The GF3 is still wicked fast, especially when overclocked a bit. You would probably see AA speed and quality improvements with the GF4 due to the Accuview Antialiasing tech. Is it worth it? Not for me. Maybe for you.
