If by stepping you mean replacing CPUs, then you can easily look that up. All cpus have a certain socket, meaning the physical connecter where the cpu connects with the motherboard. Intel likes changing these a lot, and every time the socket changes, so does the motherboard. Your current motherboard should have a chipset name, such as Z170 or B360. Look up that chipset name, then it should tell you what socket said chipset uses. The i7 3770 uses a socket LGA-1155, so if your motherboard also uses that socket, then you should be fine upgrading.
Another thing to take note of is BIOS updates, because sometimes a motherboard will be released before the CPU you are using is, so the manufacturer doesn't give the motherboard instructions for how to run the CPU. Look it up on google, it's pretty easy to do as long as you have a flash drive.
