I'm building my first desktop after using a Pentium laptop for 17 years. Because of current memory prices, I chose a DDR4 setup: 32GB of Kingston DDR4-3600, a Palit RTX 5060 Ti 16GB, a Gigabyte B760 DS3H AX DDR4 motherboard, and a Deepcool 850W Gold power supply. I'm currently using an Intel Core i5-12400F.
I chose LGA1700 because I'm more familiar with Intel and liked that the platform supports both DDR4 and DDR5, at least with different motherboards. In the future, I'm considering upgrading to an i7-14700K and passing my i5-12400F to my father, whose current system has an i7-3770K, 16GB of DDR3, and a GTX 1050 Ti. I also have a Deepcool LE360 V2 AIO available for a future upgrade.
I don't need to make the upgrade immediately, but I may be able to afford it after saving for a few months. Would moving to the i7-14700K be worthwhile, or should I keep the i5-12400F until it no longer meets my needs?

If you eventually buy a 14700K, purchase it new if possible and update the motherboard BIOS first. Earlier 13th- and 14th-generation Intel chips were affected by voltage and stability problems that are addressed through newer firmware and Intel’s recommended settings. Undervolting or using reasonable power limits can also reduce heat and improve long-term reliability.
LGA1700 is effectively a finished platform, so moving from DDR4 to DDR5 later would require finding a compatible DDR5 motherboard as well as buying the memory. It probably isn’t worth planning around that upgrade. If long-term CPU upgrades are the priority, an AM5 build would offer a better path, but that doesn’t make your current 12400F build a bad choice.
The i7-14700K would be a major performance upgrade, especially for demanding games, streaming, rendering, and other heavily threaded workloads. However, it runs hot and draws considerably more power than the 12400F. Your 360mm AIO should help, but you’ll still want good case airflow and sensible power limits.
I wouldn’t upgrade just for the sake of having a faster processor. The 12400F is still a solid match for an RTX 5060 Ti, so use it first and see whether you actually run into CPU limitations. If your main goal is helping your father, giving him the 12400F later could still be a worthwhile improvement over his 3770K system, but there’s no need to decide now.
I’m not buying the upgrade immediately. I can save for a few months if DDR5 prices remain high, and I’m mainly considering the 14700K because I could eventually pass the 12400F to my father.
