How badly have I lost the silicon lottery?

[Memo]

I have a Ryzen 7 1700 and GTX 1080 setup. I game at 1080p resolution and I noticed that my CPU is bottlenecking my GPU severely at stock speed. I wanted to overclock it abit, but the problem is that my CPU is absolutely trash at overclocking. It sometimes wont even boot at 1.3V just for a 3.6Ghz OC.... Most people on forums say they get this speed stable with around 1.2V.
I can't bump my voltage further because I use the stock Wraith Spire cooler. I looked into buying a better cooler but, I'm a total noob when it comes to assembling PC parts together and the process of removing the old cooler and setting up the new one seemed very complicated.

So what I really wanted to ask is, would it still be worth it to invest in a better cooler even though my CPU needs very high voltage for small OC, if it can ever become stable when overcloked.
Thanks for all the help and advice! Much appreciated.

It will run cooler and maybe quieter but a better cooler will not make the system boot if the cpu doesn't like its settings or the memory settings.

I agree with @Hotwired, if it's failing to boot it's very unlikely to be a CPU voltage issue. Not too familiar with the current AMD CPUs but I'm assuming it has a voltage for the IMC (integrated memory controller) as well? Is the RAM speed beyond the standard range for the CPU? It is running very tight timings? Overclocking CPUs these days isn't just a case of a single voltage setting unfortunately.

my RyZen 7 1700 did 3.9ghz @ 1.385v so for what you are using to get 3.6ghz is perfectly fine, you will need a better cooler though, I also wouldn't say that the CPU is bottlenecking your GPU at all, there are loads of tests on youtube between the 2 without any issues, however, you've not mentioned which board you have or which ram you have, also as stated above, there is indeed a separate voltage adjustment for the memory controller, its called CPU SoC / NB voltage in most bioses unless you have an ASUS motherboard who just like to use strange naming schemes for the different voltages, most people bump this one upto 1.10v as soon as they start overclocking on ryzen, stock is about 0.900v
