Nvidia Pascal cards still exhibit high-refresh-rate "power bug"

A while back, we reported on a weird issue with GeForce graphics cards and multiple-display setups with refresh rates higher than 60 Hz. The short version is that connecting multiple high-refresh-rate displays to the DisplayPorts on a GeForce card causes it to run at much higher clock speeds than the Windows desktop would seem to demand, increasing power draw and heat production. As Pascal cards start to trickle into the TR labs, we figured it was as good a time as any to revisit this issue and see whether it's been ironed out. Sadly, the problem appears to persist with these next-gen cards.

First, a brief word about our test setup. The particular graphics card we're using is Gigabyte's GeForce GTX 1080 Xtreme Gaming . My test bench has two monitors on it: my personal Eizo Foris FS2735 , a 144-Hz FreeSync ...
