Check your CPU temps. You may have messed up the heatsink mounting and its overheating causing throttling

Did you update your Intel drivers? If you're still running on the I5-4690k windows drivers, of course you'll have problems. Before changing your CPU, you also have to do a CMOS reset, so that the motherboard adapts to the new CPU model.

Check cpuz and see if cores and speed is recognizing correctly. Sometimes windows doesn't automatically.
