My first reference 7970 had coil whine as well, it occured only during benchmarks and game menus and was tolerable. Then i switched to 680 and had with it major stuttering problems so i went back to amd. And now this wf one squeels like a pig while actually gaming, so its unbearable. Im gonna take dc2 top in exchange now. From what i understand those cards dont have coil whine problems.
