Okay this is my second penryn mbp pro and while everything on it is flawless, i have one small problem. when ever I play a game such as wow, a buzzing sound will occur. It seems related to the gpu or logic board. I can hear the buzz with my volume halfway up as well. I also hear the buzz when scolling on the internet, if the site has any sort of pictures or graphics. If i set the max fps on wow to 30 it will also reduce the buzzing noise a little? I might keep this computer and return it when the sandy bridge processors come out? Is it alright to have that buzzing noise? If it is my logic board or gpu, would it be anything to harmful to keep me from using it. Or is this not really a problem and me using it won't damage anything.
