Phenom II X4 840 @ 3.56 GHz, 8 GB GDDR5, and a R9 380

I just switched from my GTX 760 to a 380 and noticed a difference in the wrong direction for playing games. When I try play Overwatch my fps seems to stay around 40 or 50 fps and drops to 20 on low settings. I tried a couple fixes which didn't work i got a slight change but nothing that great. I used MSI Afterburner to watch my CPU while I played a match and it was constantly maxed with the lowest being 90% usage.

Fixes so far:

Uninstall Nvidia drivers
Reinstall AMD drivers to 16.5.3
Reinstall AMD drivers without Gaming Evolved (guy told me to do it thought it was worth a try)
Reinstall again.

If you guys have any suggestions that would be awesome.

Thank you!

+TheTBeast Your CPU is clearly bottlenecked by your GPU. There are two possible causes: (1) Excess heat from your new GPU is causing your CPU to thermal throttle OR (2) The performance balance between your CPU and GPU are off, naturally creating a bottleneck effect.

Recommendations coming.... below

*** Scenario #1 ***

* download and run HWMonitor; play game, monitor CPU temps and report back to this thread (download link below)
* If temps are high than take photos of the inside of your case and respond back to this thread with imgur link, so that we can get a sense of your case airflow

*** Scenario #2 ***

* keep the GTX 760
* return the R9 380 (use proceeds to upgrade CPU / motherboard / RAM
* sell the Phenom II X4 840 used on Ebay; proceeds will be approximately $40 - $50.
* sell the motherboard and the RAM; decide if you'll make more selling CPU, MB, RAM as set or individually.
* buy i3-6100 or i5-6400 + Z170 MB + DDR4 RAM. i3-6100 $125; i5-6400 $190; Z170 MB $80

Addendum:

*** Ebay selling prices of Phenom II X4 840 ***

Question: BTW you wrote "8 GB GDDR5" in your description. Did you mean that your R9 380 was the Nitro version with 8 GB of VRAM, or were you referring to your system RAM, which is either DDR2 or DDR3 ?

I checked the temp in Afterburner after a match and the CPU temp never went over 39 C thanks to water cooling but at idle the GPU temp is 47 C. Didn't check GPU temp during game.

I can afford to upgrade my CPU without selling everything. Excuse my ignorance but why do I need to use the 760 if the 380 is a better card?
