Today an EFI Firmware Update has been released which is supposed to solve problems with the target display mode! So I really hope that means the Radeon HD5000 series can now be used with the iMac. Could anyone try and tell? Because I would get back the HD5770 and replace my HD4870 again ;-)...

It doesn't seem to have DisplayPort so I wouldn't choose this one. BTW my Palit Sonic HD4870 works perfectly :-).

Did anyone try a HD4870 to use the iMac as a display? I sent back my HD5770 and got a HD4870 with DisplayPort in a forum. But everybody's writing about the HD4890. I never read about someone who got the HD4870 working.
