Well I think it's AMD's problem, they still need to fix this because you know that new cards are usually have buggy drivers. Be patient for a moment if you would like.
I only run into problems like that when the framerate is extremely high. Normally it'll be a menu or other static image. Turning on v-sync can help get rid of it. It may not be the video card either. It may be the power supply. I had a motherboard that would cause my power supply to squeal.
Don't you think I need a new supply?
my old PSU has been using since i7-920, 2 and half year with no squeal.
