Even i hv been using the nVIDIA Ge Force FX 5200 (256 MB DDR RAM) graphics card for the past 1-year and that too without any problems with the latest drivers installed jus recently from this site:
*www.nvidia.com/content/drivers/drivers.asp
ANd the latest ForceWare version for the nVIDIA Ge Force FX 5200 is 71.89 wich will update ur video BIOS driver version to 4.34.20.27.06
Also make sure that u hv the latest updates/patches for ur Intel motherboard,sound drivers and BIOS wich u can get it from here:
*www.intel.com/products/motherbd/index.htm?iid=HPAGE+header_products_motherboards&
and yes as keith and anuraag have said,there is no sense at all to use a Direct-X 8.xx version on a Direct-X 9.0 and Open GL 2.0 supported graphics card....
cheers n peace....
