You're probably using a DVI connection to your monitor instead of an analgue connection. My TFT will run on analogue at 75Hz or digital (DVI)60Hz at 1280*1024 resolution. The new TFT's are digital as you can get improved sharpness etc. that way, and the higher refresh rates aren't needed as much.
Unless you are a serious gamer there's no point really in upgrading your graphics card. The Radeon 9000 Pro will keep you going for quite a while yet. Even if you were to upgrade you may not notice a huge, if any, performance increase, depending on the rest of your system spec.
Yes - just to add to the above - the persistence (the length of time the image stays on the screen if it isn't refreshed)on an lcd is much longer than a CRT - thus you don't need to refresh it so quickly to get a flicker-free image.
The downside of the same factor is that lcds are prone to "ghosting" with fast moving images.
It's ironic that in the early days of CRT monitors, much effort was put into reducing the persistence, to avoid ghosting - now we have to have the same effort all over again with lcds.
