The FX6300 is about as powerful over all as an Intel 2500k, but because that power is in 6 threads and not 4 they are all individually weaker.
Some games use all available threads and the FX will perform very well. Definitely not bottlenecking a GTX970 at 1080p resolution.
In older game engines that don't thread well it will fall behind a little, but usually not so much you would notice
The FX 6300 doesn't even come close to the i5 2500k game performance wise, the 2500k even beats out the FX 8350 in most games, and the 6300 isn't even close to the 8350. That aside, we are talking about processors that are 4-5 years old now, it's old technology. Check out this video, it shows the 2500k beating out the FX 8350 in most games demonstrated.

Also note how much more consistant the FPS is on the 2500k than the FX 8350. You will find that most AMD's seem to stutter a lot. That aside, we are talking about processors that are 4-5 years old now, it's old technology.
