Nup, your all good on bottlenecks.
Motherboards wont bottleneck anything attached to it, unless you try running a graphics card in a 4x slot or something like that.
Pro-Tip. Can halve the RAM to 8GB is its just a gaming rig. Then spend what you have saved on a 128GB SSD, as 64GB gets used up fairly quickly.

Though he is a bit off with the component pricing. Your $200 CPU will adequately support your $400 graphics card.
