Your choice of cpu and motherboard options are far from budget oriented...
-I5 9600K is a poor long term investment. Some newer games already run like crap on this cpu. It also doesn't come with a cooler, which is an added expense.
-None of those motherboards are for the budget-oriented either. They're all premium products.
Ryzen - 2400g/2600X/3600 - combined with a B450 motherboard, would be a better investment.
9700K and 9900K are the only cpus on Intel's end worth a darn at the moment.
