In the quest to build my first PC, I have encountered a problem: the bottleneck.

From my basic knowledge I would assume a bottleneck is inevitable, as one component will always be more capable than the other.

But my question is which will be the bottleneck here between a Fx-6300 and R9 270?

Additionally, if someone has any links to explanations of how to determine which the bottleneck will be for future uses that would be welcomed.

Neither one. The FX-6300 can keep up with the R9-270 just fine. Gfx cards aren't generally referred to as being a bottleneck to a CPU. They either have the power to render the frames at the required settings fast enough for game play, or they don't. But they do not "bottleneck" a CPU. The CPU has plenty of other work to do.

If the CPU is running at ~100% usage and the gfx card is well below that, the CPU is holding back the card. That's CPU Bottleneck.
If the gfx card is running at ~100% usage and the CPU is well below that, the card is rendering as fast as it can. No GPU bottleneck, but it shows that the CPU can still handle a faster card.

You generally don't want both CPU and gfx card to be running at 100% usage if you can...
