maybe he found something like this:http://www.pcupgrade.co.uk/productdetails.asp?ProductID=5671&categoryid=538
but honestly i've never thought that 9800GT with GDDR3 exist before this guy mentioned it. i look around and i found one like above.
if you want 9800GT its better to go with one that has GDDR3 module. on the other side ati new card is already out so you might be able to get stronger ati card with cheaper price (48XX series)
