Re-installation of windows is recommended, if you change motherboard.
If you change cpu but keep your current motherboard, then re-installation is not necessary.

Usually the windows licence is joined to the motherboards LAN module. Changing the CPU should not cause any problem. Better then the 4790 is the 4790k. Anything else has different socket and requires a motherboard change as well.
Connect Windows support, they can help you activate the operation system after the upgrade.

No. However if you change generations from 4000 to 6000/7000/8000 it can help with stability. If you change brands then 100%yes with out a doubt.

Couple of things to consider before upgrading your CPU. Depending on your motherboard model, you may not be able to do much with an unlocked CPU versus your current locked CPU. So, what model of Asus motherboard are you using?

Also, even with a new unlocked CPU, you won't get a massive increase in overall system performance just by swapping the CPU. You need to consider the relative costs of adding the new CPU vice the gains you achieve.

To measure the difference gained, just run a benchmark app before and then after the swap. Easy.

I am currently using Ryzen 3 3200g and using its integrated graphic card. Lately I purchased a Video Card (RX 570) which makes the integrated Graphics useless. Question is, should I reformat my PC if I replace it with my newly bought Ryzen 5 2600? or it's fine to just replace it and play?
