Since Ati has not been able to supply enough spec-speed R580 cores for
the X1900GT to satisfy current demand, they are quietly dropping the
core clock spec from 575MHz to 512MHz and trying to compensate by
increasing the memory speed. The 'derated' product will STILL CARRY
THE SAME PRODUCT NUMBER, so anybody expecting to buy a X1900GT in the
near future needs to be alert to this change, especially if they have
any GPU overclock expectations. Any purchaser of the X1900GT should
check the GPU clock specification on the board manufacturer's website
before purchase and the default GPU clock speed after purchase.
Anyway, with the (hopefully) imminent arrival of the X1950Pro,
purchasing a X1900GT is now not to be recommended AT ALL, especially
if one is looking towards a current or future Crossfire setup.
The X1900GT is being phased out in favor of the X1950Pro, which uses
the RV570 chip with an integrated compositing engine, finally
allowing symmetrical Crossfire using SLI-style bridges with a pair of
these cards. ATi is 'quietly relaxing' the X1900GT spec to push out
as many R580 cores as possible before shutting off the product. Not at
all surprising from ATi's business perspective, since the R580 is a
large and extremely expensive die.

for the full details on the X1950Pro and the issues with regard to the
X1900GT.
The article's author Derek Wilson has some very harsh words for ATi's
deceptive marketing practices with regard to the unannounced changes
in the X1900GT specifications. See page 2 of Derek's article.
