I know this has been asked a million times before, but exactly how much of a performance difference would i see between a 6600gt and a 6800gt. the 6600 has higher clock speeds, but fewer pipelines. As far as i know these are the only differences. I would like a card to play games at the highest resolutions with everything on max if possible and also a card that will be able to play tomorrows games decently as well. I know things change quickly so that may not be possible, but i would appreciate as much info as anyone here can offer.
