I was running EQ2 with an Nvidia FX 5200 card and it was choppy, laggy and very low quality.
I broke down and bought an ATI Radeon 9800 pro All-in-wonder card and it looks beautiful now.
I'm curious to see how future cards will run EQ2. Unfortunately my Asus P4P800 Motherboard does not have a PCI-Express slot, so I'm stuck with AGP 8x. As far as AGP 8x goes, you can't go wrong with the ATI card.
I hope this isn't a big no-no. :) Set me straight if it is.
