Wot does ma PC support..?

[backfromhell4u]

I wanna upgrade my PC so I can finally play some of the latest games available. Right now I have the following (v.old)specs of my PC:
PIII 863MHz 128 MB RAM OS-Windows XP
Motherboard-D815EEA2 4X,2X,1X Universal AGP Connector for AGP Add in Cards
3 DIMM Sockets for 133-MHz SDRAM Memory Up to 512MB

I am almost sure to upgrade my RAM to 512 MB. But the graphics card is a problem. Which graphics card would support my system and have direct x 9.0 compatibility. Please suggest which models of Nvidia Or ATI would be ideal for my PC and would work on it normally.
