I am trying out a Radeon 9800 pro to try and improve the performance and graphics on my computer.  I was wondering if someone could suggest how  I should adjust  the settings in the video card to get the  best out of it. such as the antialasing, mip apping,perfomance, resolutions etc.
My computer is a AMD Athon (tm)
XP 2500+
1.84 Ghz
1.0 GB of Ram
