WE SPOTTED A LINK at a very famous Italian web page about a card that Nvidia didn't want to talk about at least not so far. Hardware Upgrade wrote here here that there will be more Nvidia cards on the Geforce 6800 marchitecture then Nvidia is actually telling any of us. 
They already made the statement that the 6800 Ultra card clocked at 400MHz core and 1100MHz memory will cost $499 and that the 6800 non Ultra will be clocked at 350MHz core and with 700MHz memory and these cards use DDR1. 
The third card that Nvidia hasn't spoken about is the 6800 PRO - very unusual choice of name if that is the final one. This card should fit in between the Ultra and non Ultra, and be clocked at 350MHz for the core and 1000MHz DDR 3 for the memory. 
The Italians suspect that this card will end up with 12 pipelines and we suspect that it will be around $399. 
This card should directly compete with the R420, soon to be officially named the Radeon X800PRO.
