[Bug] 2.0.3 Multi-GPUs

[helrich]

I currently run 3 monitors. The middle monitor is run off of a GTX 580 and the two side monitors are run off of a GT 520. When
tuning the 580 (GPU Link mode OFF) the two side screens start artifacting and spazzing out until the driver eventually crashes
and everything resets. I'm wondering of the 520 simply isn't compatible with GPU Tweak?

PSU wattage?
Overclocking or even under clocking?
Tried other Software such as EVGA's Presission?
