CPU speed relation to NVMe and SATA 3 SSDs

[SusieCue]

I'm looking for some sort of benchmark/comparison between some systems for my own curiosity. I'm reading into cpu bottlenecking with newer storage mediums.

Example: Some cheap Intel Celeron processor with a Samsung 960 pro NVMe SSD, vs something like an I7 7700k with the same thing, with enough ram to do the job.

Backstory: I'm transitioning from an AMD FX-6300, 16gb ddr3 with a SATA 3 SSD, to an i7-6800k, 32gb of ddr4 and I'm weighing the real-world performance worth of upgrading from my 500gb samsung sata SSD to a 500gb M.2 NVMe SSD. All I plan on using this drive for is for windows 10 pro, a couple VMs running XP with 16gb of storage allocated, and ubuntu with 32gb of storage allocated respectively, and down-time with some user files and a few light games saved to it.

The drives are about 200~250$, and if it isn't really going to knock my socks off, I might just stick to my SATA SSD which is still in good shape.
Thanks in advance, guys!

A conventional SATA III SSD has a 6gb/s SATA limitation.

NVMe has around 32gb/s.

Improvement is vast, but one thing few note is that not EVERY NVMe drive has the same rates. Some are slower, thus cheaper. And, by way of processor speed alongside this, a higher end processor will work better with a higher end NVMe drive, rule of thumb. Not to say ANY processor wouldn't work- but, if you have enough money to practically have a NVMe drive.. you can get a worthwhile processor.
