AMD ATI will show Radeon HD 2000 series graphic cards at Tunis today. But now it's said that the mainstream DX10 warrior from AMD ATI would run at 800MHz core speed and 2200MHz video ram speed. But 128-bit GDDR4 may hurt its performance under 16x 12 resolutions with AA and AF on. See more detail.
Thanks kenofstephen for providing the Radeon HD 2600XT picture
