Good luck to you, my friend. I built what I consider to be a monster; I'm running a dual core processor with a GeForce 7950 GX2 and I still have to turn off shadows to maintain a steady 30+ FPS.
I think we're going to have to wait for a 64-bit OS so we can max out RAM and slap together a QUAD SLI system to fully "max" out EQ2 in the graphics department. Maybe in another year or so. Hopefully.
Still, the game has never looked better at 1920x1200/60 Hertz on a Dell 24" 2075 FWP monitor.
