Not for sure if all MSI MBs support it, but if yours does you can download <A HREF="http://www.msi.com.tw/program/support/software/swr/spt_..." target="_new">Live Update</A> and update your BIOS from inside windows. I was a little worried when I did mine on my K7N2-L, but it worked great without problems.
If you post a link to your 3DMark results in the graphics card forum a bunch of people will come out of the woodwork to fight over how you should speed up your system and get more 3DMarks or bungholeos or whatever.
Does your BIOS let you play with memory timings, and if so do you have everthing set as fast as it will run stably? Do you have AGP Apurture set to 128MB (or 64MB)? Do you have AGP Fast Write turned on and VSync turned off? Do have an option to enable Fast Command Decodes, and if so is it enabled?
