[SOLVED] Measuring benefits of a fresh Windows 10 install

So I've been planning on doing a fresh install of my OS and documenting the benefits of a fresh OS after years of bad software/driver build up. Any good suggestion of what benchmarks to run and what things to measure, testing methodology, etc? I have some ideas myself, just wondering what others thought.

Specs:
4770k
RTX 2060
32gb 1600mhz ddr3
256 adata SSD
3TB seagate HDD

In some ways this is a worst case scenario when it comes to just a messy software/hardware/driver history, or at least worse than an average user. Don't judge me.

Brief History:
This OS started on an HDD on an FX8320 build with a 750ti, was cloned to an SSD, upgraded to a 1060, upgraded to a i5 4460, upgraded to a 4770k, upgraded to a 1070, upgraded to a 2060. So 3 CPU's, 4 motherboards, 6 GPUs inlcuding a few very old (2006) GPU's Nvidia and AMD, a couple different backup HDD's some of which failed while in the PC, 3 different cases, 3 different PSU's, SSD is pretty full...
