You guys think this will bottleneck?
depends what you use it for.
no matter what you can come up with a situation where you'll be bottlenecked.
what resolution and framerate are you hoping for?
and on what games?
There is always a limiting factor, or bottleneck. What are you buying for that build? What are you trying to do with it?
To be frank I wouldn't buy that CPU/Motherboard for the same money you could get a Ryzen 2600 and appropriate motherboard that would be much more suitable regardless of what your gonna use it for...
