Test overheating

I was planning ryzen 7 2700x new build but as now 5000 series launched Ryzen 5 5600x and ryzen 7 5800x the price of ryzen 3700x and 3800x falled down but the price if ryzen 2700x increased and I got in mind that I am investing rs 20k for ryzen 2700x which is outdated and 2018 launched...
