I think an AI board is a fantastic idea. Simply put having smarter AI characters in game would make my gaming experience so much more immersive. There's nothing more jarring to a good game experience than having to shout at dumb henchmen aggroing at the wrong time, getting stuck on walls or doing something stupid. Also rememeber that gaming isn't just about FPS's there are a lot of games that would really benefit from a dedicated AI board. Strategy games could be the next big thing with a decent AI. MMORPG's with decent enemies that don't just blunder around on preset paths or follow the player in a train. There are loads of concepts that haven't been explored because of no way of programming a decent AI to handle it. Still the idea of buying another board is a little daunting now, but so was buying a gfx card in the beginning. As for making a motherboard with a slot for ppu and ai chips, isn't that called a console?
