Not sure what to think of this...
Honestly thats a strange thought, its normally the opposite problem (not enough power) now its too much power. Thats actually kinda funny and ironic in a way. Either way im sure most of the mainstream ones are fine or will show to be fine, but its just those off brand ones to worry about.
I dont get what is the point of the low power state for desktops is though...
Yeah I agree, I mean in most cases on the upper end spectrum, we want more power and I doubt the effects of this are really important because how often will the CPU be under low enough stress to make this valid. Thats just my honest opinion, because if im not using my PC for anything, its off most of the time.
