You have a good processor, don't worry. In some very CPU-dependent games, a better micro would be appreciated, but don't obsess over the bottleneck, buy the graphics card you want and enjoy it.
As an example, I have put together a friend with an Nvidia 1050 GTX TI graphics card. My friend with a micro much inferior to yours like the Intel Q9650 now plays WOW very fluidly in Full HD. It has given a few more years of life to a platform with almost 10 years behind it... so imagine with a more powerful micro like yours what a modern graphics card can do.
