ATI Eyefinity HELP QUICK

ok i've done alot of research about the eyefinity for a widescreen (landscape) 3x monitors extend for gaming on 3 screens
i know how to do this i need either a display port monitor or a displayport to dvi adapter (vga works to but not as good)
passive one DO NOT WORK
active ones do since they supply the extra power (usb) but i was wondering do all active display ports to dvi work with ATI's eyeinfinty?

im looking at this one >>>here<<<
hopefully you can inform me cause i dont want to buy a useless item

i know sapphire has made a single dp to dvi but they have flickering issue on some ghx cards (text under pic)

also i want this one
if you know an aussie site that ship within Australia plz link

Check with dell as they use the same adapter. Not sure if its available there or not.
