I recently purchased an EVGA 550ti for some nice gaming on a budget. The card produces some decent visuals for sure, but whenever the card has to do anything graphically intensive at all I get this strange whining sound coming from my audio outs.

The sound is similar to air being let out of a balloon very slowly so that it squeaks; it's a high pitched whine that is just loud enough so that I cannot ignore it, but I can still hear whatever I need to gaming/movie wise. It comes from any set of speakers that I plug into the computer, and when I plug in my headphones the volume output of my software doesn't affect the sound. The pitch of the sound changes depending on the graphical load on my card, and there's even a whine when I do as little as look at a gif or other small movie.
I read a couple other threads about similar issues but I couldn't find one with specifically the same problem. Please help! I just got this card a couple days ago and I really want to avoid an RMA.
Ok, I just tried that and it had the exact opposite effect! I actually muted the output from my onboard sound and then the noise was directly correlated with the volume of my external amp. However if I plug in my headphones instead of using the amplifier I can still hear the noise.
I played around with the settings and if I run the computer at MAXIMUM volume with all applications and then keep my amp as quiet as possible, the resistor in the amp is actually helping to reduce the noise. However it's still audible, just not quite as annoying.
