I was wondering what kind of game engine Everquest uses? Is it a single threaded or multithreaded? Also, does anyone know if Sony Online Entertainment plans to change the game engine anytime soon? The reason I ask is in CPU selection. Debating between an E8400 Dual Core and Q6600 Quad Core. Would I notice much of a difference playing the game between these two CPU's? This is really the only game I play, and want to design a system that will last for a few years. Either CPU will be paired with an 8800GTS G92 512MB video card. Thanks for any comments and suggestions. I just do not know a whole lot about the designs behind software and games nowadays.
