Pretty sure I need an external sound card, but looking for some opinions.

So here's the thing. Recently (3 days ago) I've had this awful buzzing noise that comes through my microphone. However, it only happens when my gpu is under load. The buzzing even changes pitch based on the amount of load/fps. Any other time, its crystal clear.

My specs:

CPU: i7-2600K
GPU RX480
MOBO: Z68AP-D3
SOUND: Onboard, Realtek HD
MIC: Blue Yeti USB

So, after hours of trouble shooting here's what I've found out:

-The mic is fine on its own. I tested it with 2 laptops, no buzzing.
-The gpu is 99% the reason for the emi buzzing. I ran benchmarks using iGPU with the 480 unplugged and no buzzing at all while under load.
-PSU is non-issue as I swapped it with my cousins and the buzzing was still there.

So, as far as I can tell, from reading others with similar problems, its EMI from the GPU causing the buzzing in my microphone. Others can hear it, its very audible, even with noise gates.

So, what do you wonderful people think? Should I just hit the trigger and pick one up? And if I should, what do you recommend? My budget isnt much, roughly $50. I can go a bit higher, but not much.

Thanks for reading. ♥

Update: Went ahead and bought a Xonar U7 for cheap. Buzzing is still there. Totally lost, emailed Blue to see about an RMA as its still under warranty.
