Upgrade my CPU processor a bit

Base clock between the K and the S is only out by 30mhz which is nothing and it base which is also not really a big deal because you will be boosting when the processor needs to work fast. But if you can get the K for the same price you think then you might as well.

Well its would be between better eco or 30mhz less eco, i don't think it matters either way, all though the S would be slight better for improved temps and less power draw where extra 30mhz base is not going to achieve anything.

The only time base would matter if you were going to lock the cores and OC to a target, like an extra 1ghz basically on these CPU if you have all the prevsions to do that but you can't and probably won't on a OEM system unless you really know how and even then it would be hard to do.

It wouldn't harm to buy 3770K, provided it is not much more expensive than the regular 3770 and he can afford it. Unless he tries to overclock it, performance should be the same as 3770. I would check the BIOS first for overclocking options. Can you increase the FSB? Is there an option to change the multiplier? Can you adjust the CPU voltage to compensate? If the answer to all these is yes, then go for 3770K if the price is reasonable. Otherwise go for 3770. Even if you don't consider overclocking now, you might want to do it in the future. As I say it is better to have some features you won't use but miss features you might need. Avoid 3770S, the clock difference might be small but why compromise? You don't buy a CPU every day, so you want to get the best for your money. The highest and fastest possible CPU for his motherboard is 3770 or 3770K, it wouldn't be wise to settle for less, unless the cost difference is too much. How much you find 3770? How much you find 3770S? If the difference is small go for the best, that is 3770 don't think about it! You will thank me later.

Since 3770 and 3770S are at the same price it makes sense to buy the regular 3770 to have maximum performance. Don't even think about the 3770S. Go for the regular 3770. If you are on a tight budget you don't want to experiment with nonsense! Buy the best you can afford and have peace of mind for many years. If you make a bad choice now you will regret it forever. Why compromise when you can have the fastest? And yes, 0.30Ghz difference is a lot, contrary to what another poster claimed. We are talking about GHz here, compare 3400MHz vs 3100MHz, now the difference doesn't seem negligible, does it? Make no mistake, go for 3770, period. You are welcome.

If he doesn't play any games, I advise to maximize CPU where he will immediately notice the difference in performance and add a discrete graphics card later. The opportunity to buy an Intel 3770 CPU is present now, it may not be available in the future since it is an old component, don't lose that opportunity! He can buy a discrete graphics card at any time, maybe not the 710 but a 1030 or newer. They all are suitable for his system as long as they are of the PCIe type, while to find a 3770 might prove much more difficult. Don't lose this chance! Go for the 3770, everything else (GPU, RAM, faster/larger SSD) can be added later.

When win10 expires what will happen to all those old machines ?

S is £40 in the Uk
i7-3770S

non S is £30 in the Uk
i7-3770

You know there is nothing stopping them from going to w11 they will just miss out on some security. Which much of is trivial we have been computing mostly without this stuff until now. These features are good to have but they aren't going to break legacy systems from continuing.

They won't miss anything. They will be the same secure as when running Windows 10 with the same configuration and the same applications. There is a misconception that running Windows 11 on unsupported systems makes them more vulnerable than running 10. Absolutely not. Nothing changes, as long as you have identical configuration.
