Hey man,
I own a FX 6100 the lil brother of the FX 6300, Its doing fine but im noticing that lately it just isnt going to get the job done and not in the future for sure. I recommend getting an i3 6100 from intel, getting a working used i3 6100 is good too, wont cost alot and will also be future proof!
the i3 6100 does work faster than the FX 6100 / 6300
