currently, no Radeon cards support Dual DVI. Actually, if u use ur AIW 9700 pro, use the DVI out, and for the secondary out, use the component out. Component is just as good as DVI, the only difference is that Component is a digital signal sent over an analog device, but a very high quality analog device, DVI is a digital signal sent over a digital device. Similar to SPDIF Coaxial and SPDIF Optical, where optical is the pure one, and coaxial is the almost-pure one. Monitors that use component in should becoming more popular, especially with the rise of HDTV as any HDTV will have component input. However, if u want true dual DVI, look at the workstation cards from ATI, the FIRE GL Series, those got dual dvi.
