ATI´s RV570XT becomes the X1900 GT
 

The firm is currently shipping X1900 GT cards based on R580 chips that have the pipelines crippled but the card based on RV570 XT will be far cheaper to produce. ATI is likley to confuse the market with the current plan and we think it will find a way to differentiate the old X1900 GT and the new one, so there might be some more numbers or letters added on.
