And its still the same crap... artefacts and decreased performance when running Crossfire...

ing unbelivable, after spending 700€ on this POS....
ok this might not help, but I have had similar problems with crossfire on Vista 32 bit. Have you tried any 64bit operating system? 32bit would give me odd screen flickering / corruption while running 3d apps with crossfire enabled. Nothing like that on 64bit Windows 7. I didnt try to debug the issue on 32bit as I had it on my old hdd which i use for suicide bench runs :p
