We managed to get a peak in what might be the first mainstream DirectX 10 AGP card ever. ATI has the reference design and this sub $200 product should be ready by the end of the summer.
The Radeon HD 2600PRO works at 600 MHz core and 800 MHz DDR2 memory. There will be a two flavours one with 256 and one with 512 MB of memory and both cards will have dual DVI + a HDMI out.
It also looks like the cards will have an external floppy power connector as AGP can not provide enough power to the card.
