just recently got my new 4k samsung monitor, which works great.
but i have massive fps drop on gaming while crossfire is on.
take a look at this:
ULPS : OFF
Watt drawn from wall 317W (Reminding i own a 850w SeaSonic Gold )
Crossfire : Off
Fps is about 65-70
GPU usage %100
Watt drawn from wall 320W :
on all the games i tested, crossfire decreased performance (1st GPU:40% Usage, 2nd GPU:100% Usage) Dota 2,CS:GO,DmC,GRID2,COD:AW
both gpu usage were above 90% and clocks were good. PSU was drawing 150w more than usual (450w), are these good news? now its a driver/profiles issue?
is 450w a legit draw for cf use?
It seems like we have a power issue, but i think my psu is strong enough, drawing 300w on cf is surely aint enough.
I'm gonna let you Experts help and save my day, Thank you.

I very much doubt it's your PSU.
What do you get at lower resolutions, in terms of GPU usage and performance?
Can you try more games to see what they do?
