The VGA connection causes this in some way. On the DVI monitor the screenis OK, but those scan lines appear in the VGA one.
However i was able to play CoD2@333fps without any problems at all on my old GPU..

@Mitch thanks but already installed that one too

heat is also no problem, my rig is open and not warm at all..

Also that noisy humming sound stays on the DVI as well even with unplugged VGA monitor
