For most general computing operations, I find my 1GHz@1.2GHz to be more than enough. My system has a lot of snap in Windows. It is definitely quicker than even newer computers that aren't properly configured and tweaked. For tasks like that, the HDD plays a bigger role than the CPU once you pass 1GHz.
However, in games, the CPU is started to show it's age just a little bit. I don't even think I am tapping the full potential of my Radeon 8500 with this CPU. I am about to re-unlock the CPU (I can only use up to 8.5x currently) and try to overclock it a little further for an intermediate boost. I would say that the middle of this year will be about the time I have to upgrade. I would wait just a little longer. It is always good to wait until you can't stand it anymore. Then, you can get faster equipment when you goto upgrade and save some money at the same time.
