Installed brand new R9 280X's CPU usage gets to 100% whilst gaming

Solved by DIRTYHACKEROOPS,
I have found a Solution to this problem!!!!
I am running Crossfire R9 280X's and dealt with major fps drop when enabling crossfire. However when I had it disabled (when I had the game running on one GPU) I would get almost always 60fps on ultra (with AA). After some research, in fact a lot of research I fixed this problem by disabling frame pacing and enabling fullscreen in game. I was running the game on borderless the whole time and this was the cause of my problem. What borderless and windowed do is they mess with your crossfire settings. It gives one GPU (in my case GPU 2) all the work but lets the other one spike up and down inconsistently. Mine would frequently drop to 30% load then back up to around 60% load (I checked the load using MSI afterburner and EVGA Precision X). If you don't understand what the last couple of sentences meant well.. then either you shouldn't have a gaming PC or I just really didn't explain well.
Im just messing, Its ok to not understand. Just do as I said, Disable frame pacing and enable fullscreen under the video settings IN GAME! you should then be good to go. I went from 30-40 fps all the way up to 60-80fps on Ultra (with AA)
I hope this worked for you!
