I run 2 monitors one large for games and one small for multitasking. Its been the case for a while that multi-monitors would cause the GPU to act funny at idle specifically the VRAM doesn't downclock. But the 290 is way worse than anything I've seen before. With 2 monitors it idles at 60C-70C. The second I unplug one of the monitors the RAM downclocks and the idle temperature returns to a sane value. Measuring power consumption with my UPS my idle draw from the PC increases ~50w from having 1 monitor to 2. Really strange and hopefully AMD can do something to fix it in the future.
