Last week we took a look at the Battlefield 2 demo's performance with the latest and greatest high-end cards, today we're evaluating performance with a handful of mainstream cards. We've gathered ATI's RADEON X600 XT, X700 PRO and X800 256MB, as well as GeForce 6800 and GeForce 6600 GT. Our goal? Figure out which cards delivered the best performance and image quality. See the results inside!
