gpu dont bottleneck cpu right?

yes a gpu can bottleneck a cpu. If the cpu is waiting for the gpu to finish a task.

The site isn't even encrypted, which should tell you something about its quality in 2017. It appears to be a platform for Google ads, likely hosted by a single person.

It shows my system as having a 19% bottleneck at the CPU, and if I were to upgrade to a 7700K, a 16% bottleneck, likely because of the lack of PCIe lanes available to my 2 GPUs, yet a 5960X with 40 lanes has a 10% bottleneck (with simulated DDR3, for direct comparison). Even though it's generally agreed upon not to use a site like this, at least we can demonstrably prove why now. But what this proves is that there is always a bottleneck somewhere.

I know for fact that a real-world in-game test of my exact GPUs on a 6900K nets me about a 5-10FPS increase in 2K full settings on most of the Bethesda titles, in which I average 80's to 100's. If you're building a rig purely for benchies or folding, you might think otherwise.

The whole premise that website is based on—that you can plug in the names of two products and get a flat percentage to describe a bottleneck—is already completely wrong. That already tells me that anything it spits out is going to be meaningless.

At the very least it needs to know what game you'd be playing, because the amount that one component is being bottlenecked by something else shifts around constantly based on the workload. That percentage should be completely different in Starcraft II, Doom, and Battlefield 1. Hell, it wouldn't even be a flat number in each game from moment to moment.

Also, that website tells me that I should upgrade my i5-6600K to an i7-3930K of all things, and that's such a random and bizarre recommendation that I suspect it may just be shooting out random CPU names at me.
