The cpu won't bottleneck the GPU, like I said it can handle much stronger GPUs. Your computer will be GPU bottlenecked, but that is not a bad thing actually. You can get a better GPU right now with a lesser CPU for the same money but that will limit your upgrade options in the future. Or if you can really afford it get a higher GPU with that CPU. What resolution do you use for gaming? What kind of game settings are tolerable for you? Is that PC mainly for gaming or for other purposes as well and what are they?
