Going with 4 core 4 thread CPU in 2020 is in my opinion not a good idea. I have a 6600k which is same as 7600K, but it has slightly lower Processor Base Frequency and Max Turbo Frequency. Don't get me wrong, it's still a good processor for daily use, but in modern game i can see it can struggle and it's hitting close 100% usage which is not good. Btw new games are better optimized for higher core count CPUs.
If you are low on cash and are in no rush wait till the release of the new Ryzen processor. When that happens all the Ryzen 3000 will get a nice discount
