ATI has decided to lift the NDA on their new series of cards. Rumors have been circulating the net on the card's amazing performance, and now we have some benchmarks and reviews to look over. Those with crossfire capable boards may find these especially interesting.

Yeah, these seem like they are going to replace the 8800 GT for best bang for buck.

Current MSRP is $199, rumored to drop $179 sometime early in July.

AMD back in the game.

looking over the screenshots on pc game hardware... truth be told im more sold on the gx2/280 ... most of the benchmarks these days are poorly constructed, showing only the closest 2 cards on the market... seeing the spread like that, and with most gaming machines running over 2k these days, a few more hundred on a GPU with results like that would be very worth it
