I guess you need a special version of the card or something tho, mine only has 2 DVI ports, 1 HDMI port, and 1 VGA port.
The reference 5870's only support eyefinity up to 3 monitors, which one has to be a native display port monitor. So this means no going DVI DVI HDMI, as one DVI and the HDMI are on the same output source.
Future eyefinity cards whether it be future 5870's and 5890's may support up to 6 monitors. However, this requires the manufacturers to put 6 outputs on the card itself, which in turn will drive up costs, and price of manufacturing.
