Why buy Intel? Just get an AMD Ryzen 5600X and you’ll be doing better then anything Intel has on the market.
Clearly he is looking for a value option, not the best. A Ryzen 5 5600X is hardly a "value" CPU at $300. A more likely comparison would be a Ryzen 5 3600, but even those are going for $30 more than the i5 10400F on Amazon ($200). Also keep in mind that the Intel CPU will play a lot nicer with his DDR4-2133 than a Ryzen would, so that is another cost consideration.

Did a research from google and i found a pcbuild website to calculate i7 6700 + rtx 2060 at 1080p bottleneck
Don't look at bottleneck calculators. They are completely useless and I have no idea why they exist whatsoever. For 1080p, you have a nice CPU/GPU combo. The 4c/8t might limit you in more open world games but only about as much as the 2060 would anyway.
