Think I found a solution the issue:

Having the same issues w/ my setup; 2014 Macbook Pro 15" w/ Retina+ Akitio Thunder2+ GTX 980Ti+ Focusrite Scarlett 18i20 Audio Interface. With everything plugged in, and no stress on the GPU, there is no noise/interference. When GPU is under stress; through rendering, gaming, etc. , there's interference/noise that correlates with the amount of stress to the GPU IE: Low stress=very very little noise, Higher stress= more noise. It isn't unbearable or anything, it's just annoying to deal with; pretty much only noticeable when there's no other audio playing. It's weird b/c... When the audio interface is being plugged in (via USB) while powered off, but my monitors/speakers are powered on, the interference can still be heard. ~ vs. When the audio interface isn't plugged into my computer (via USB), but my monitors/speakers are powered on, there's no interference at all. My Akitio+GPU is less than a foot away from my audio interface, so I suspect it's from elctromagnetic interface like the dude above said. Suggestions?
