Is it bad to have 12% bottleneck? Only play Fortnite and warzone

When all games run the way you want…
12% bottleneck… At best that's a rough estimate. Has hardly anything to do with reality.
A GTX1060 / 1070 is said to be the maximum that can be supplied by a 4770 with enough data.
Consider the CPU clocking at 3.5 GHz on all cores at best. And the IPS (core performance) performance is really not that great anymore.
The CPU brakes considerably more (the performance is slightly below a 4770).
But no that's not bad.
There are benchmark tests in which you can easily read this out, but your 12% "bottleneck" (that's really a gruesome word for it) is not a real number.
Put your system under load and check which component is lacking, i.e. Which component is fully utilized and what is not, then you see in black and white where your bottleneck is.
But it can be said simply that your CPU does not harmonize particularly well with your GPU, the CPU (a server CPU) is totally out of date and your GPU is too new.
You have probably also installed DDR3 RAM, which is also not the best.
So if you want to get more performance or the maximum performance from your GPU, you need a new CPU, there's also a new board on which the new CPU fits and then the RAM should also retire.
