Although this was posted in the forums a couple of days ago, there is now some more official news of the first ATI HD 2900 XT using GDDR4 memory that will be available for retail, as well as a few more places to purchase it. The card will initially be exclusively available from Diamond Multimedia, featuring 1GB of GDDR4 memory along with all the other 2900 perks such as built in HDMI and 5.1 surround sound. The card will officially be launched on 14th June, and the current list of retailers is as follows: Biohazard Computer Systems, Extreme PC, Falcon North West, Maingear, Memory Express, NCIX, Smooth Creations, Velocity Micro, Vigor Gaming, XI, ABS, Cyberpowerpc, Polywell, ibuypower and Canada Computers. Pricing is generally around $650, and most of those sites should accept pre-orders. Presumably this is essentially the HD 2900 XTX, as that was originally going to be the 2900 with GDDR4 memory, however the name is still XT - perhaps ATI has more to come in the HD 2900 series? At present this should be the most powerful ATI card.
