Question is 3% bottleneck bad?

How do you get a 3% bottleneck without knowing what games or resolutions you will play??
Bottleneck calculators are junk science.

There is no such thing as "bottlenecking"
If, by that, you mean that upgrading a cpu or graphics card can
somehow lower your performance or FPS.
A better term might be limiting factor.
That is where adding more cpu or gpu becomes increasingly
less effective.

One rule of thumb is to budget 2x the cost of your processor for the graphics card.
