Have come across a link to this site when browing through EQ2. Everquest seems to be one of, if not the most demanding game on the market right now. But as most people are aware its not always the hardware that gives you better performance. I have been able to notch the setting up by one, by installing XG Warcats 5.9 XT. It looks to be a hybrid set of ATI Catalyst drivers. If you need that extra bit and don't mind straying away from the standard, i would say give it a go. looks like they do NVidia there too.
In my opinion it's a 100% must have.
