Your motherboard is not suitable for a FX-8350.

Moreover, few games can use more than 2-3 cores.
For most games, it is the performance of the master thread that matters.
Your FX-4100 master thread passmark rating is 1220.
FX-6300 is 1409.
By comparison, the single thread rating of a modern skylake i3-6100 is 2085.
core speed is most important for games such as strategy , sims, and mmo.
Games such as fast action shooters depend more on graphics cards.
Only in the arena of multiplayer games with lots of perticipants does many cores help.
Here is my stock approach to finding out what YOU need:
------------------------------------------------------------
To help clarify your CPU/GPU options, run these two tests:
a) Run YOUR games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.
b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.
You should also experiment with removing one core. You can do this in the windows msconfig boot advanced options option. set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many cores.
If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.
It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.
