When it comes to AGP cards and their ability to interact with today's game programs and the use of 9c or 10 versions of Direct X, you have the best card. I have one myself. However, as time does go by and software is rewritten to take advantage of 9c and 10, your chances or playing these Titles are going to diminish. I bit the bullet and built a gaming rig with a dual core AM2 board and installed a PCIe card in there that can interface with latest 9c and 10 versions of Direct X.
To enjoy and enhance your game play on what ever servers your connecting to, I would not hesitate to question the techs for the site on how to configure my card. The AGP card you have is a good one and well known. You have a good chance of getting some pretty decent suggestions on how to setup your video settings, etc. to enjoy the best experience you can.
I know this is nothing but a pep talk on the card and a hint of suggestion to build a better rig, but don't fault your card just yet. Ask and get involved in the online forums for your game and you'll get some Tips and Hacks for the card without any problem at all.
Good Luck,
