Just got this for my powerbook to hook up my 2 Dell 24in flat panels that I got for $750 a piece on sale new. Its a pretty awesome card. Perfect picture just like it is coming off the native DVI port. Check it out. Good solution for those of you who want to hook up dual flat panels to a powerbook G4 15 or 17 incher.
