Windows 10: Should I upgrade what I have or buy a whole new PC?

    If you have money ... Yes buying new system is worth it .... i mean Kaby Lake.
    I looked up Kaby Lake on wikipedia (Kaby Lake - Wikipedia) but I don't really get it. The processors all seem to have the same names as before. How much faster is a Kaby Lake processor likely to be than what I've got in my old system is it likely to be in practice?

    The 'Ask Jack' feature in the Guardian of 19 January gave a detailed discussion of the different processors, including Kaby Lake. See: How can I tell if a PC processor is any good? | Technology | The Guardian

    Gads - what a total mess Intel are making of their branding.
    I had a look at the link the article cites: Mobile Processors - Benchmark List - NotebookCheck.net Tech
    and the only think I could find that looked similar to my Intel "Core i5-720" is their "Intel Core i5-7200U", which seems to be 157th position which seems pretty good to me.... so no need to upgrade??
    But I don't really understand what's going on. The fastest process appears to be "Intel Xeon E5-2697 v2" and the second fastest is a "Intel Core i7-7700K" and have no idea how much faster either of those processors will be likely to be in practice in a desktop. All v confusing.

    That's only applicable to Notebook processors which are much slower than the actual PC processors.

    This should make more sense Best Processors January - 2017

    I come back to my first proposal. Long delays in loading progs are not a hardware problem when you have an I5 with enough memory. It's just most likely an overload of unwanted programs running.

    You owe it to yourself to get someone to check on what is running and run adware checks. You could do a lot worse than run Malwarebytes followed by ADWCleaner. When you know your computer is running only the stuff needed, then you can assess hardware requirements.

    I can assure you that swapping an I5 for another I5 is not going to provide the miracle you seek.

    I run a similar configuration to you and it runs very well indeed, but I do know to check for unwanted startups.

    My existing processor is a 7-year old "Intel Core I5 750 2.66GHz". According to that page (Best Processors January - 2017) my CPU is at position 123 (out of 184) with a "3D Fire Strike Physics Score" of 4260.

    The fastest CPU is a Intel Core i7-6950X with a score of 19740 which is 4.6 times faster.
    The fastest "i5" CPU is a Intel Core i5-6600 with a score of which is 3.3 times faster.
    The processor that I was offered in my quote from PC Specialist is an "Intel Core i5-7400" which is only 1.4 times faster.

    So only 40% faster...? In seven years PCs of equivalent cost have only become 40% faster!
    Whatever happened to Moore's Law?!

    I agree that all the salesmen I have talked who keep claiming that on old i5 is way, WAY slower than a modern i5 are simply trying to "blow smoke up my ass" as the Americans would say.

    So yes, it strikes me that there is absolutely NO point in upgrading my hardware. At least that is true if I can cram a decent modern graphics card into my existing motherboard - in order to run a modern higher res (i.e 4K or possibly QHD) monitor, which from what I can see it sounds like I can.

    I think that Moore's Law has stopped working, at least as far as processors go.
    They can't keep making the bits on silicon smaller and smaller without it all going a bit quantum.
    CPUs still get better, but the old days of doubling of speed every couple of years have gone.

    So it seems. What I don't know is where the bottlenecks really are/where.

    Overall, how much faster would one reasonably expect a computer to have become in the last 7 years?

    It's not so much faster but more a case of better implementation probably additional features maybe more cache and a better more efficient chipset on the newer motherboards.

    I wouldn't go to much on the firestrike figures that's one IMO poor benchmark.
    See here for a direct comparison between the i5-750 and i5-7400 UserBenchmark: Intel Core i5-7400 vs i5-750

    There is a physical limit on how small connections can be and how close (quantum effects can become significant in the extreme) and how fast signals can be transmitted reliably over metallic conductors; until technology changes significantly, there won't be a step change. Optical computing anybody?

    It depends what you are trying to do.. just how fast does the hardware have to be to do what you normally need it to do? On my first 366MHz laptop with a 10Gb drive (that was BIG) I could browse the internet, send emails, play music, watch DVDs.. sound familiar?

    Sure, voice recognition, games, VR, more demanding applications- you need bigger faster more capable hardware.

    Clearly the mechanical drive is a fundamental constraint.. so we have SSDs.

    A Guinness world record for processing telephone calls in a telephone exchange was won with 2MHz custom processors. That was at the point when Intel was first publishing plans for their family of pentium processors.

    Multiple cores and multiple processors normally add little value in domestic situations. That's a different matter in massive data processing - say climate models, or analysing the output of the LHC. But most of us don't do that every day. So you probably can't rely on architectural change to provide huge perceived improvement in a PC.

    Much of what we do is increasingly reliant on being connected. There are so many possible constraints there. Yet apparently MS is planning a sort of light-weight generic Cloud Windows where parts of the OS are downloaded on demand. You can't browse quickly over the fastest connection if the server is your main constraint.
