I too hv an Intel D865 GBF mobo with 512 MB DDR RAM(hynix) on a P-4 2.00Ghz processor and i am using a medium range graphics card from nVIDIA wich is the Ge Force FX 5200 (256 MB DDR RAM) card and i am very well satisfied with its performance (as of this present moment..
)
Most of the ppl here will suggest u to go and buy the ATi range of Cards as they perform (only) slightly better in (some) games and other graphics related options coz different ppl hv different tastes...
U can try out the nVIDIA's GE Force 6 series of cards on the site mentioned above wich will be suitable for ur configuration
also go for a card wich is available in ur area and with good after sales support(in case of any future problems with the card)
happy hunting Bro !!!
Cheers n peace..
