Upgraded from a i5-6400, Huge improvment. Before I wasn't able to run Warzone and discord together, running virtual machines was slow aswell and gaming performance was potato reaching up-to 100% cpu utilisation on every triple A level game titles which left no room for my PC to work on other tasks. Paired with a 3060ti, the 6-cores and the increased instruction per clock (IPC) now allows it to carry out tasks without a CPU bottleneck, as of early 2022 it runs every game perfectly without an issue.
The stock cooler isn't great when the CPU reaches 4ghz+ you'll be reaching high of 70 degrees (Very Hot) with the fan speed maxed out which can be annoying as its very loud and without proper airflow (which is a must) can heat up and even melt your side panel. One way to solve that would be to get a custom air cooler or lower the maximum processor state that way it will never reach 4ghz but it be a lot quieter and still give great performance. If your going with a 3rd-party cooler with this CPU and have good airlfow, then I reccomened it, however if you're on a tighter budget than I reccomend the 12400 as a better value for money option.
