ATI's X600XT faces end of life in December
 

WE SAW SOME official documents which are indicating that ATI's X600XT cards will reach the end of their life as the fourth quarter ends.
ATI made this decision since it's not that easy to position X700 cards together with the X600s. However, they will just eliminate the fastest of the X600 cards, the X600XT, while X600PROs will continue to coexist with X700 cards.

The X600XT is being replaced with the X700PRO card. In Q3, X600XT used to cost exactly as much as X700PRO but costs now in Q4 a magic $199.
