depending on the type of 9800se (what you have), it may be possible to "softmod" to get MUCH better performance without anything but a software install. if you have a 9800se with 256-bit ram, you should download the OMEGA drivers and try the "9800SE softmod" option (or something like that). if this results in artifacting/checkerboarding, you can turn it back to normal by re-installing the drivers.
